Pixel Shader Version Supported: PS1.1, some limited PS1.4 shaders to render terrain in less passes
We're CPU limited initially, all three graphics accelerators sat waiting for the CPU to send them more data to work on, via the graphics driver. The Radeons move 20% ahead at the median setting, the XT shadowing the slightly faster XT PE at all times. At the upper setting the NV45-based board is only ~8% slower. What's also interesting is the PEG16X X800 XT taking a rough 2.5% lead over the faster XT PE board. Surmising, we see that the interface is possibly having an affect at the upper setting.
