d-r-t kernel, HD4890. Since - commit ce44bae366ade59fb2dbdfbfe5a1ab8d24518a57 Author: Marek Olšák <maraeo@gmail.com> Date: Tue Jan 3 22:01:03 2012 +0100 u_vbuf: implement another upload codepath which unrolls indices Improves performance from cca 1 fps to 23 fps in Cogs. This new codepath is not always used, instead, there is a heuristic which determines whether to use it. Using translate for uploads is generally slower than what we have had already, it's a win only in a few cases. I get quite a noticeable perf regression running demo1 in nexuiz. Other games (openarena,ut2004 demo, etqw) seem unaffected 91.2740132 fps, one-second fps min/avg/max: 50 99 231 (90 seconds) to 55.6802612 fps, one-second fps min/avg/max: 19 69 231 (90 seconds) Sometimes I saw a couple of short (1/4 sec) stalls as well, which gave worse results, above was without stalls.
Fixed by 2bdf93449a0b00145fabdd3f7866acbafa18e734. Closing.
