My problem stems from being unable to run both SEUS (Sonic Ether's Unbelieveable Shaders) and ChromaHills at the same time. I can run either just SEUS or just ChromaHills just fine, with no lag at all, but not both. When I try I get the message from the NVIDIA OpenGL Driver "Your hardware configuration does not meet minimum specifications needed to run the application. The application must close", and then it crashes. I'm on Win 7 Professional 32 bit, 4 gigs RAM, GeForce GTX 460, AMD Phenom 9800 GT quad core 2.21 GHz (old, I know).
SEUS + OptiFine/ShadersMod and ChromaHills on 1.7.4, Need help
