Many games run around 50%, which means there's a lot of room for improvement. Currently 80% of Windows performance is a high water mark, few games run faster.Watch out for high wineserver CPU usage.Don't fix too much on such warnings, they may indicate a comparatively minor problem. Sometimes Wine knows it hits a slow path and writes a FIXME or WARN. No background processes consuming CPU time, etc. If it runs at the same speed there's probably nothing Wine can do to fix it. Make sure you actually have a problem: Test the game on Windows on the same hardware.Rules of thumb can be wrong, so some intuition, double-checking of assumptions and deviations from the guide are necessary.ДЎ) Basic steps for debugging Direct3D performance problems:Д«efore digging too deep check a few common issues: Note that 'unlikely' below doesn't mean 'impossible', neither does 'likely' mean 'always'. It needs careful debugging and may be tricky to fix. 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.ДЇirst, the bad news: Often there is not a magic bullet to improve performance. There are also a few graphic debug tools that might come in handy, like apitrace or renderdoc. sysprof newer, easier sampling whole-system profiler for linux.oprofile (classic sampling whole-system profiler for linux, can profile into kernel, too).Here are a few that have been used with some success: There are many profiling tools that can help find bottlenecks in Wine.

#Wine emulator performance how to

is a shell script that knows how to download and run several of them.ДЈDMark 06 in particular is a classic benchmark we'd like to do better on. 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.

(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).

is a thread about kernel configuration and Doom3/Quake4/Prey performance.

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 ).

CONFIG_NO_HZ might make a difference, for instance. The linux kernel might have something to do with performance.

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 ).

applications that are picky about what core a thread runs on may be disappointed (see e.g.

applications that use kernel events heavily may run slowly (e.g.

applications that rely on precise thread scheduling will be disappointed (see e.g.

#Wine emulator performance driver

('winetricks glsl-disable' helps some games with this, as it translates D3D bytecode into the lower level ARB_program language rather than GLSL and the driver is generally quicker at compiling those.

applications that frequently compile D3D shaders may suffer from stuttering see e.g.

component does not contain d3d or unknown.

Here are some performance-related bugzilla queries: The rest of this document is meant for developers more than users. (For instance, suggests Batman Arkman Asylum runs a lot faster if you set MotionBlur=False in that same file.)

anything listed on the web as speeding up the Windows version.

For instance, says Batman Arkham Asylum runs a lot faster if you set AmbientOcclusion=False in UserEngine.ini.

anything listed in the appdb as helping your particular game.

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).

#Wine emulator performance drivers

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.

That disables a bunch of error checking and validation

if you run your game from the command line, run it with WINEDEBUG=-all.

#Wine emulator performance code

Notice that sometimes it enables code paths that aren't well tested (or are plain broken) in the game

if the game has an OpenGL mode, you could try using that.

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