What is System RAM and GPU requirements ?

Hello.
What is amount of system RAM used by RPCS3 ?
What is the memory requirement when using Windows 10 64 and RPCS3 ?
What is the minimum Nvidia GPU card ? 600 series ?
The emulator use the GPU just for video render or for some code emulating the SPUs using the floating processing of GPU card ?
Thanks.

Hello.
What is amount of system RAM used by RPCS3 ?

Depends on the game and the settings used. The most I have seen is about 3-4 gb (rpcs3.exe only that is), that was in Catherine with the LLVM recompiler.

What is the memory requirement when using Windows 10 64 and RPCS3 ?

8 gb total will work fine.

What is the minimum Nvidia GPU card ? 600 series ?

600 series actually based on Kepler for DX12 and Vulkan. I think 400 series will work with OpenGL. (Some 600 cards are rebranded 500-series cards that only support OpenGL)

The emulator use the GPU just for video render or for some code emulating the SPUs using the floating processing of GPU card ?

The GPU is only used for GPU stuff.

Thanks.
