When you hit a memory limitation you fps generally drop to if your lucky 1 to 2 fps. I hit that limit lots when doing a bunch of SLi bug fixing with nvidia back when I was running dual 8800GT's (SLi adds additional overhead that would just go over the 512 megs of ram on the cards). The same thing in windows would happen as well to the same crawling results. Interestingly enough when you ran SLi in DX mode it would not hit that same memory limit. It also seemed to be limited to Ungines benchmarks.

It is the only parameter holding back Linux domination.
I do quite a bit of gaming under GNU/Linux. I've listed some of the games I've finished under WINE here:
I'm running a i7 950/GTX480 setup, but even so this is a great topic to look at. I know a long time ago WINE had a huge performance hit on lots of the games I played. Either that's not the case these days, or my newer hardware generally makes any difference unnoticeable. I'm interested to know which.
It's not the only thing, but it is a big piece of the puzzle.

I suspect this is the case in OpenArena, but in my past experience the locking didn't affect performance more than lets say 10%, but perhaps it can be worse here in Quake3 based games. (Did you test without sound?) Anyway under normal conditions as you see in things like Heaven performance is the same.
The locks are necessary to support multithreaded D3D devices.

Thanks a million for your excellent reviews and benchnak testings. I als way appreciate them!
I hav just one point that pains me and shurely 20% of the male viewers of your reports. 20% of all men have a red/green colour weakness. this means to view the charts with red and green (and often brown) lines can not be seen by us.
Please have mercy on us and use mor distintive colours. My I humbly suggest blue, orange, red (or brown or green [one of those is fine but not two or all]) black, white, gray.
If you even want to get one step better use different kinds of lines: dotted, hyphens, dot hypen dot etc.
I know we make up only 1/8th of the worlds population, but still be so kind and do not discriminate against a minority of 800 million people.
Thanks in advance!
