It is recommended to use a modern GPU with at minimum 4GB VRAM. It is possible to be GPU/VRAM limited at native resolution with weaker/1GB-2GB GPUs and iGPUs, to determine if you are throttling when under these conditions, lower your game's resolution and see if performance improves. If you lose noticeable performance when playing at a higher resolution it means you are GPU/VRAM limited and your graphics card/VRAM amount is not sufficient to maintain said resolution without a performance loss. GPU power and available VRAM is not very important unless you want to increase your game's internal resolution or reaching higher FPS limitiations. Intel Integrated Graphics (iGPUs) are not officially supported but have decent compatibility.Ī comprehensive list of all known current GPU-vendor specific bugs and available workarounds in Cemu can be found here - GPU Compatibility List
5 times your physical RAM as Initial size(MB) and 1.5 times your physical RAM as Maximum size(MB).
Altering your pagefile size may cause your PC to become unstable, resulting in crashes of your entire system.Īlternatively, some users suggest to have a custom size of. It is recommended to have a pagefile on an SSD or the fastest drive available, and to leave pagefile size as System managed size. Your GPU vendor can also play a role in what your RAM usage will be in Cemu and will determine how essential a pagefile is, or how often it will be used, if at all. One way to see if one is using a pagefile while using Cemu is to see their "total commit size" in task manager and pay attention to if the number shown being used exceeds the amount of physical RAM installed within your PC, as pagefile usage is typically not shown under RAM usage statistics. Instead of crashing immediately when exceeding RAM limit, you may experience lower performance when a pagefile is used and may also experience additional in-game stutter when swapping. PageFile: A pagefile (virtual memory) is essential to have in order to avoid crashing when running out of available RAM. They are much faster than SATA drives and therefore less likely to become unstable and crash with lesser amounts of RAM. Solid State Drives (SSD) are a boon to users with lesser amounts of RAM, as your PC will push data to the PageFile on your SSD if you set it to do so. If you run out of RAM and have a very slow SATA HDD, you are either likely to stutter relentlessly in-game or you may possibly have Crashes. We recommend at least 8GB RAM for most games, but preferably 16GB+. Not practical to use on pre-8th generation i5 and pre-6th generation i7 Intel CPUs, and most 4-core CPUs. Triple Core Recompiler a minimum of 4 to 6 Cores + Threads available. Not recommended for Dual Core (2 cores+threads) CPUs system instability.
Dual Core Recompiler a minimum of 4 Cores + Threads available. This experimental setting allows extra cores to be utilized for PPC CPU emulation instead of 1, however not many games actually utilize multiple PPC cores and currently causes stability issues/crashes or offers no benefit for most titles.
See the Recommended Settings section for what is recommended under CPU Options / Affinity.
I wouldn't recommend going under a score of ( 1,800 ) if you plan to play Breath of the Wild at 1080p 30FPS (Native Wii U Framerate) This list ranks CPUs for Single Thread IPC: You can check out Darkemaster's AMD FX Compatibility Video list for Cemu 1.12.0 and for 1.15.3~1.15.8 Single Thread IPC and Overclocking are the most important factors for how well CEMU will perform on your PC!
