Game Profiles are specific configurations for individual games these allow the user to set the options used when emulating a specific game. This allows the user to load a game without needing to reconfigure Cemu every time.
Note: If no value is set in the Game profile, Cemu will use the setting chosen when selecting options inside Cemu.
loadSharedLibraries = true
If set to true, system rpl files will be loaded from /cafeLibs/ if present. Default value is true
useRDTSC = true
Use RDTSC instruction as timer source for emulated CPU, OS and audio
accurateShaderMul = true
If set to true, Cemu will correctly emulate the non-IEEE behavior of the shader MUL instruction. Can fix graphic issues but also decreases shader performance and increases shader compile time. Default value is true. # Since Cemu 1.7.5 the option accurateShaderMul also supports a third mode, enabled by using the value 'min' (e.g. accurateShaderMul = min). In this mode, Cemu will emulate non-ieee MUL instructions in a more GPU-friendly way which generates less complex shaders. However, this mode might not be 100% accurate
UseSeparableShaders = true
If set to
false Cemu will use the Conventional Shader system from pre-1.8.0.
disableGPUFence = false
If set to
true, GPU fence operations will be skipped. Default value is
false. Enabling this option can lead to instability and crashes
GPUBufferCacheAccuracy = 0
Controls the accuracy of vertex and uniform data caching. A higher accuracy means more expensive checks which can slow down rendering. Possible values: 0 = high, 1 = medium, 2 = low
streamoutBufferCacheSize = 24
The buffer cache size of the streamout buffer in MB.
extendedTextureReadback = false
If set to
true, Cemu will try to mirror data written by GPU operations to CPU RAM (but only if access by CPU is assumed to be likely) Default value is
cpuTimer = cycleCounter
Timer source for OS and CPU time. Supported values are
hostBased (timers are based on actual OS time) and
cycleCounter (timers are based on speed of emulated CPU).
emulateSinglePrecision = true
If set to
false, the recompiler won't correctly round the result of single-precision instructions in certain situations. This can introduce gameplay bugs, but might also improve performance.
cpuMode = Singlecore-Recompiler
CPU mode. Possible values:
Finding Game Profiles
Game profiles are stored in the
gameProfiles folder of your Cemu installation. When a game is loaded, its matching game profile will be used. To see what profile is being used, load a game and find the TitleId in the title bar of the window or look in the log.txt file after loading. Search for the TitleId inside the
gameProfiles folder without the dash to find the file Cemu is using.
