The ‘Aspect Ratio’ is defaulted to 16:9 but can be 4:3 depending on your monitor. The ‘Graphics Device’ is the card in your system but only used if ‘Vulkan’ is specified. Vulkan is another option which allows you to specify your graphics card with GPUs if you should have an Nvidia or Radeon graphics card.

The ‘Renderer’ is how the graphics are managed. The settings here are for the graphics processing. The second tab is the ‘GPU’ tab as shown in Figure 2. If larger options are chosen then the SPU size is increased to lower the number of SPU compiled units. Usually it is best to leave it on ‘Safe’. The ‘SPU Block Size’ can be used to help some performance issues. The ‘SPU Cache’ should remain enabled but can be disabled if the cache becomes too large. ‘Enable SPU Loop Detection’ can be important but in some cases can cause audio stuttering if enabled. ‘Lower SPU Thread Priority’ is only useful on a Core i5 or lower. The ‘Enable Thread Scheduler’ should only be checked on an AMD Ryzen CPU or else it has not use. The ‘Additional Settings’ has more settings which can be changed. This should be a safe default for most games. The ‘Firmware Settings’ should default to ‘Load libv2.sprx only’. If a game should ‘stutter’ you may choose a smaller value. Choosing ‘Auto’ will use the the maximum number of cores. If you have eight cores then you can use any number between 1 and 8. The ‘Preferred SPU Threads’ are the number of cores you want to use. LLVM Recompiler (fastest) – Fastest running mode but start times are slower and less compatibility for more games.ĪSMJIT Recompiler (faster) – Same as the ‘LLVM Recompiler’ but not experimental in this decoder..Interpreter (fast) – Allows games to run faster but may affect compatibility.Interpreter (precise) – Slowest mode but helps on some games if they crash a lot.

The first tab is the ‘CPU’ tab as shown in Figure 1. The SPU is similar to a GPU and performs computations for the graphics. I should mention here that the PPU performs physics computations to help with gravity, items colliding and the like.

Once the new window opens you can start making changes. The Configuration options will vary depending on hardware but once you have the settings the way that works best you will be set.Ĭlick on the ‘Config’ icon at the top of the RPCS3 window. It may be best to set up the default for as many games as possible and then change specific settings for individual games. Your next step is to set up the default Configuration for the games. Once the Firmware is loaded you are ready to go. A window opens for you to find and select the PUP file. Once you start the program, select ‘File’ and then ‘Install Firmware’. Now you only need to execute the file to start it.
