They are there mostly for older games that are incompatible with the newer implemetations but they get triggered automaticaly from Nvidia's compatibility table.(10-23-2012, 01:59 AM)VIRGIN KLM Wrote: About the Nvidia drivers thing, It's the problem I told you with the adoption of the newer OpenGL 4.x.x since Nvidia will stop supporting OpenGL 3.x and it's on the fly backwards compatibility and will also update older cards with a substitute to 4.x.x under a slightly different name. You can expect more issues popping up one after the other. I doubt that anyone would use older drivers since that move gave a speed impact of atleast 20% making it near equal to DX11's speed which is a serious reason nobody would leave the latest drivers. All this won't happen unless somebody report to NVidia staff that it's causing way too many issues and they need to work on them or JPCSP gets updates with OGL 4.x.x implementations natively.Read this http://developer.nvidia.com/opengl-driver

FAQ 5: NVIDIA has no plans for dropping support for any version of OpenGL on our existing and future shipping hardware. As a result, all currently shipping applications will continue to work on NVIDIA's existing and future hardware.
