I and many others run desktop graphics cards off of a laptop. Performance is good when using an external monitor, but when trying to use the laptop's LCD screen, performance drops drastically due to the framebuffer needing to be sent over the compressed x1 PCI-E link. I found that forcing 16bit color depth instead of 32 provides a major performance increase, and the drop in color quality is hardly noticeable in modern games. The problem is that I only know how to force 16 bit color in windowed mode. Is there some way to modify the driver or directX to force either 16 bit or 24 bit color even if the application requests 32 bit? I tried rivatuner, but it just doesn't work at all with modern drivers.
