Hi, previously I'm using Win7 (32Bit) and PPSSPP (32Bit) working fine. However, I added RAM to my computer and using Win8.1 (64Bit), I downloaded both 32/64 bit latest PPSSPP and they both fail to run because telling me my OpenGL doesn't support 2.0; DXDIAG telling me DirectX 11 is up-to-date and the driver model is WDDM 1.1!
Can anybody help?
