UT2003, X², Quake III
Unreal Tournament 2003 now. It's patched up to 2225 and our custom demo consists of a bot match at 800x600.
There's not much I can say that the graph doesn't.
X² - The Threat begins to bunch up at around the 110FPS mark. The situation is far different for the onboard gaphics. It struggles to 20FPS. We'd not be too happy at playing any new titles with it. It's strictly for 2D work, which it isn't particularly good at.
Standard Extreme 2 results for Quake III tend to hover at around 58FPS. Another indication that low latency memory bandwidth helps to nudge up onboard graphics performance.
