I have an Nvidia 9800 GTX+ video card, with the proprietary drivers (185.something) installed under Kubuntu 9.04 64-bit. It was very easy to do, but I'm not getting the 3D performance I should.
One game where I'm having problems is Urban Terror 4.1. The game is based on a rather old engine (Quake 3) so, even at its highest resolution and detail settings, it's not going to make a video card like mine work very hard. However, despite the on-screen frame counter showing 72 fps, there's a noticeable sluggishness to the onscreen action. The animation is perceptibly choppy, and there's about a half-second delay between clicking a mouse button and the accompanying action happening onscreen.
Urban Terror 4.1 runs smooth as silk under Windows XP Pro. I could get 100+ frames per sec there, but I limit it to 72 to match my monitor's refresh rate (72 Hz) and thus prevent the "tearing" artifact that can happen when refresh rate and framerate are mismatched. 72 fps is plenty. I'm using the exact same settings under Kubuntu 9.04 as I do under Windows XP, so I should get more or less the same performance, right?
I have played Urban Terror under Kubuntu 8.10 on this machine, and under Kubuntu 8.04.1 on a very old machine (AMD Athlon XP CPU) with no such performance issues. So, I suspect I've misconfigured something, or maybe this is a known problem in Kubuntu 9.04. What say you?
