Now that Wine has matured to the point of running many applications correctly, people are expecting them to run as fast as on Windows. Sadly, this is not always the case. Here are a few notes related to tracking down performance issues.

Alias defined in bashprofile doesn't work for wine, while the same path given in CLI works. Apple ships g based on the old libstdc runtime in pre-5.x versions of Xcode and on pre-10.9 OS X. Starting with Xcode 5 and OS X 10.9, Apple is using clang and its C11 compliant libc. The C11 runtime is not compatible with the older C runtime. It is entirely possible to build the C11 runtime on pre-10.9 by itself.

User Tips

Surprising as it may be, there really isn't a magic toggle to make everything faster. Anyway, for games, you can experiment with the following short list of settings:

• if the game has an OpenGL mode, you could try using that. Notice that sometimes it enables code paths that aren't well tested (or are plain broken) in the game

otherwise

• enable CSMT (https://wiki.winehq.org/Useful_Registry_Keys)
• if you run your game from the command line, run it with WINEDEBUG=-all. That disables a bunch of error checking and validation
• enable threaded optimization in the GL drivers: you can do that with environment variables, that's mesa_glthread=true for Mesa drivers or __GL_THREADED_OPTIMIZATIONS=1 for Nvidia proprietary drivers
• disabling UseGLSL might slightly improve Direct3D performance and reduce shader compilation stuttering (but that has a chance to work only for d3d9 or older games and usually only with the Nvidia proprietary driver)
• anything listed in the appdb as helping your particular game. For instance, http://appdb.winehq.org/objectManager.php?sClass=version&iId=19065 says Batman Arkham Asylum runs a lot faster if you set AmbientOcclusion=False in UserEngine.ini.
• anything listed on the web as speeding up the Windows version. (For instance, http://www.hardocp.com/article/2009/10/19/batman_arkham_asylum_physx_gameplay_review/3 suggests Batman Arkman Asylum runs a lot faster if you set MotionBlur=False in that same file.)

Performance-related bugs

Here are some performance-related bugzilla queries:

Known Bottlenecks

• applications that frequently compile D3D shaders may suffer from stuttering; see e.g. http://bugs.winehq.org/show_bug.cgi?id=23832 ('winetricks glsl-disable' helps some games with this, as it translates D3D bytecode into the lower level ARB_{vertex|fragment}_program language rather than GLSL and the driver is generally quicker at compiling those. Only works on Nvidia, though.)
• applications that rely on precise thread scheduling will be disappointed (see e.g. http://hisouten.koumakan.jp/wiki/Linux_support#Resolved_bugs )
• applications that use kernel events heavily may run slowly (e.g. Unreal Tournament 3 - Stefan?)
• applications that are picky about what core a thread runs on may be disappointed (see e.g. http://bugs.winehq.org/show_bug.cgi?id=19748 )
• some applications don't interact well with power management and supposedly get 30% to 80% higher frame rate if you run at full power unconditionally (see http://bugs.winehq.org/show_bug.cgi?id=24558)

Kernel?

The linux kernel might have something to do with performance. CONFIG_NO_HZ might make a difference, for instance.Here are a few notes on the subject:

• World of Warcraft supposedly had pauses every 15 seconds unless you modify /etc/sysctl to change kernel.sched_batch_wakeup_granularity_ns and a couple other parameters (see http://wiki.archlinux.org/index.php/World_of_Warcraft#Kernel_Timing_Bug)
• http://forums.gentoo.org/viewtopic-t-789725.html is a thread about kernel configuration and Doom3/Quake4/Prey performance.
• http://code.google.com/p/realtimeconfigquickscan/ (you have to check the whole tree out) is a little script to check whether your system is set up for low latency (mostly for audio)

Measuring Performance

If you're making a tweak that speeds up one application, you probably want to run a bunch of different performance benchmarks before and after, to make sure it doesn't slow other applications down.

Many benchmarks exist for Windows. ['yagmark'] is a shell script that knows how to download and run several of them.3DMark 06 in particular is a classic benchmark we'd like to do better on.

Looking for Bottlenecks

There are many profiling tools that can help find bottlenecks in Wine.

Here are a few that have been used with some success:

• oprofile (classic sampling whole-system profiler for linux, can profile into kernel, too)
• sysprof newer, easier sampling whole-system profiler for linux

There are also a few graphic debug tools that might come in handy, like apitrace or renderdoc.

It's possible to build wined3d for Windows; this is cool because it might let you figure out if the bottleneck is in wined3d itself.

Game Performance Debugging Tutorial

First, the bad news: Often there is not a magic bullet to improve performance. It needs careful debugging and may be tricky to fix.

Note that 'unlikely' below doesn't mean 'impossible', neither does 'likely' mean 'always'. Rules of thumb can be wrong, so some intuition, double-checking of assumptions and deviations from the guide are necessary.

1) Basic steps for debugging Direct3D performance problems:

Before digging too deep check a few common issues:

• Keep your software up to date
• Make sure you actually have a problem: Test the game on Windows on the same hardware. If it runs at the same speed there's probably nothing Wine can do to fix it. You're free to try though.
• Make sure your System is OK. No background processes consuming CPU time, etc. Try disabling Desktop compositing
• Check for log messages. Sometimes Wine knows it hits a slow path and writes a FIXME or WARN. Don't fix too much on such warnings, they may indicate a comparatively minor problem.
• Watch out for high wineserver CPU usage
• Currently 80% of Windows performance is a high water mark, few games run faster. Many games run around 50%, which means there's a lot of room for improvement. If your game runs even slower there are probably some nasty bugs around.

Some words about CSMT. The basic idea is to segregate wined3d's GL calls to a separate thread: wined3d functions indirectly called by the application threads queue messages to the command stream thread which, on its part, essentially keeps checking the queue and executing whatever instruction it finds there.
CSMT has been initially developed as a way to enhance wined3d performance, with the 'theory' being that by splitting the potentially expensive GL calls out of the application thread we can quickly return to the application code and hopefully lessen our CPU-side woes. That turned out to work pretty well but with a caveat: some commands (e.g. mapping buffers) actually NEED to wait for the operation to complete since they have to return data to the application. Without some 'tricks' when we get one of those commands we have to effectively wait until all the commands queued before it complete their execution, which means that the application thread has to block and wait, potentially throwing a lot of the performance improvement out of the window.
The version of CSMT initially introduced in 'official' Wine does without some of those tricks (specifically, those that weren't generally safe) and has some room for further performance improvements. It still works perfectly fine as a better replacement of the StrictDrawOrdering option.

2) GPU, CPU or sync limited?

3D rendering is a complex process where multiple components have to play together:

• The GPU has to render the scene fast enough
• Software on the CPU side(driver, game, ...) has to generate rendering commands fast enough
• Software and GPU should, as much as possible, not have to wait for each other

If your game slows down if you increase the screen resolution (or speeds up when you lower it) you are probably GPU limited. This is because the CPU rarely touches single pixels, so with increased resolution only the strain on the GPU increases. Exceptions may apply especially in older ddraw/d3d7 based games..

Figuring out if the issue is excessive synchronization is a bit harder. A significant portion of wined3d time being spent in wined3d_cs_mt_finish() (with CSMT enabled) might hint in this direction, although that isn't necessarily the case and there might be synchronization points hidden in other spots.

3a) GPU limited situation:

If you're GPU limited the problem could be inefficient shaders, or incorrectly configured render target formats. Try ARB shaders (if the game is happy with Shader Model 2.0 or you have a Nvidia GPU), and check logs for usage of 16 bit per channel or floating point render targets.

Unless you have a low end GPU or play at a very high resolution GPU limitations are rare. A seeming GPU limitation may also be a sign of a software rendering fallback in the fragment pipeline.

3b) CPU limitation

Most performance issues on Mid-End or High-End systems are CPU side bottlenecks. The problem can be in pretty much every component involved in running the game:

• The Linux Kernel
• The X server
• The 3D parts of Wine
• The non-3D parts of Wine
• The 3D driver

It is tricky to tell those apart. A useful first test is comparing the following 3 metrics:

1. The performance on a normal Windows system
2. The performance on Windows while running the game with wined3d
3. The performance on Linux/macOS with Wine
4. If you are on macOS: The performance with Wine+macOS.

If there is a noticeable difference between (1) and (2) the problem is likely in the 3D related parts(wined3d, OpenGL driver). That's because all the other components haven't been changed. If there is a noticeable difference between (2) and (3) the problem is either in the non-3D parts(Rest of Wine, Linux kernel, ...). Make sure the game runs in the same codepath in all 4(or 3) cases - some games can use both d3d9 and d3d10 for example.

A difference between (2) and (3) may also indicate a problem in the Linux 3D driver that does not occur on Windows. If you are using AMD's or Nvidia's binary drivers this is unlikely because the Windows and Linux drivers share a pretty big common core. On macOS there is less code sharing, so if you're debugging performance issues on macOS the difference between (3) and (4) can matter.

3c) Limited by CPU-GPU synchronization

Ideally GPU and CPU should run as independent of each other as possible, to allow them to work at the same time without interruptions and exploit the available resources to the fullest.It's the application that ultimately decides how to set up its rendering pipeline, which means that sometimes there isn't much that Wine can do to avoid costly CPU-GPU synchronization points. That's one more reason why comparing performance with Windows is important.Assuming a well-behaved application, wined3d should strive to avoid introducing its own synchronization points. To figure out if there is room for improvement, the only practical thing to do is to look at the d3d log by hand (probably with some additional traces around wined3d_cs_finish() or its callers or other interesting points). I've also found it useful to make a log with just those ad-hoc traces (so to not slow down the game too much) and check it 'realtime' with the game and maybe perf.

4) Profilers

Now that you have a rough idea if you're looking for issues in 3D or non 3D parts it's time to separate modules further. perf, sysprof or other profilers can help here.

Case A): 3D related problems:

The main question is if the GPU time is spent in wined3d.dll or the driver. If more than 5% CPU time are spent in wined3d this is suspicious. If a lot of CPU time is spent in the driver libraries(> 30% if you need some threshold) it may indicate a bug in the driver itself, or inefficient GL calls made by wined3d. With binary drivers the difference doesn't matter much since you can't change the driver anyway.

Specifically for CSMT, a high wined3d_cs_run() CPU usage most likely means that the command stream thread is spinning a lot waiting for new commands to execute. That in turn points to the application thread not being able to keep up with the pace of the command stream / GPU execution (possibly because of wined3d stuff in the application thread) or that there is a lot of synchronization with the command stream thread and the queue is flushed a lot. A lot of time being spent in wined3d_cs_emit_present(), instead, suggests that the command stream thread is the bottleneck. In turn, that might be busy on the GPU or CPU side. In the latter case, driver's threaded optimizations might help, if available.

Case B): Non 3D related problems:

Usual suspects are ntdll.dll, kernel32.dll, wineserver, various C/C++ runtime libraries, the Linux kernel. You may be able to use the native version of the library in Wine. If that fixes your issues you know where to fix it in Wine. Again note that a high CPU usage in the Linux kernel or in low level Wine libs may be caused by inefficient calls to that library from a higher level, so be careful before taking out the pitchforks.

5) Telling wined3d problems from driver problems

Telling those apart is not easy. A driver may not support OpenGL extensions used for speedups, causing high CPU usage in wined3d(e.g. GL_ARB_vertex_buffer_object, GL_ARB_vertey_array_bgra). WineD3D may make inefficient calls causing high CPU usage in the driver.

A rule of thumb way is to try a different GPU/driver. If a game is slow on Nvidia GPUs (compared to Windows) and fast on AMD GPUs (compared to Windows on the same card) then the problem may be in the driver. If you have a binary driver you may as well just assume that the problem is in wined3d since otherwise you're mostly out of luck anyway.

If you isolate a problem in the driver don't forget to report it to the driver vendor.

6) Other hints:

• GPU vendors offer various performance debugging tools. Those can be helpful for debugging GPU or bandwidth limitations. They're usually focused on Windows, so you're probably better off by debugging wined3d on Windows
• Windows has helpful tools as well, for example VsPerfMon (Kinda like oprofile). To use those you may have to compile wined3d with Visual Studio to get Microsoft-Style debug symbols.
• Don't hesitate to contact wine-devel for help.
• Do your homework before contacting driver developers or other projects. Installing Wine and a Windows Game means a lot of work for non-Wine people, so make sure you're not wasting their time.

Wine C 2b 2b Runtime Library Error Pcsx2 Mac Os

Some users (me included) are facing a serious problem after the Booster Pack #2 update. The game will launch but crash after the intro.

This is an image of the error: http://imgur.com/a/g4O1vIt reads 'Microsoft Visual C++ Runtime Library - Runtime Error - Program ...eamappscommonThe Binding of Isaac Rebirthisaac-ng.exe - This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.'

Contrary to what it might seem, it's not a library error, but a corruption of the save file that happened for some users after the booster pack #2 update. To make matters worse, since the game already started once, Steam now has this corrupt version of your save file in its cloud and keeps downloading it to your computer, making it impossible to play the game even after reinstalling.

This guide will help you get your save file back and safe and the game working. I already tested it with two fellow members from this sub, besides myself. Please, link anyone with this problem to this post. It might help them a lot.

Wine C%2b%2b Runtime Library Error Pcsx2 Mac

FIRST, IT'S IMPORTANT TO...

1. Make sure Afterbirth+ is enabled in your DLC list on Steam. If it's not, it'll show your save files as corrupt even though they are not.
2. Follow these steps very carefully, and pay special attention to your backup files. If you delete them, you might lose your progress forever.
3. Keep in mind that this guide is for Windows only. If you're on Linux or Mac, you probably know how to adapt the guide to suit your OS, but I can't currently help with that.

1) Let’s get the backups of your save files and place them somewhere safe.

Go to the My Documents/My Games/Binding of Isaac Afterbirth+ folder. That folder’s contents should be:

1. a log.txt file detailing the crash
2. a options.ini file where you can edit the game’s settings
3. persistentgamedata1.dat, persitentgamedata2.dat and persistentgamedata3.dat <- these are the current save files the game is using. They are corrupt and will need to be deleted.
4. The backups of your save files that the game seems to keep around. They are named similarly to the save files themselves, but are prefixed by a YYYYMMDD date. For instance, 20170522.abp_persistentgamedata3.dat is the backup of my third save slot, taken on the 22nd of May, 2017.

Copy and paste all of these files somewhere safe. The important files are the backup ones, but since we don't know which one we'll need, you bett
