Doom3 Linux and Windows Battlegrounds

Doom3 Low Resolution
Below, you can see how our cards performed under lower resolution on both Windows and Linux. Texture Sharpening was disabled in all tests. Obviously, since we could not run these tests at 16X AF on Linux for all cards, we had to turn the settings down to 8X AF on Windows. (We talk more about the 16X issue in the IQ section of this analysis.) Both platforms are using 4X 9-Tap Gaussian AntiAliasing. All tests were taken with default settings in game (other than resolution).
Notes From the Lab
Feel free to check here how our Linux testing fared on Windows from the Doom3 launch. Derek uses a slightly faster machine with slightly different testing parameters, but it should give you a general idea of where our results scale on Windows.Unfortunately, it's fairly ridiculous to think that you will run the game with any of these settings on a 5600XT.
At this point, we are looking at ulterior meanings to Timothee's statement. Performance ranges anywhere from 25% to 15% worse on the Linux platform fairly consistently. Performance looks OK, but we certainly can't expect our Linux platform to outperform Windows in this portion of the analysis.

#15 - My bad to make such generalizations..but the fact that you can't even use an ATI card to play D3 doesn't bode well for Linux gaming...

#14- bunk. All you can take away from this review is that Windows "owns Linux for" D3 1.1 performance. You can't generalize this for game performance in general. Most games show a less than 5% difference.BTW, another article on the same topic with more detail is at http://www.linuxhardware.org/article.pl?sid=04/10/...

I like the difference pictures.. although when you get up to 8x and 16x, they're probably unnecessary.But the thing to take away from this review is that Windows owns Linux for gaming performance.

Interesting article. Was it just me or are the difference maps just pure black? Also I dont think things like 16xAA are really needed, after 2x or 4x the differences between anything higher and the original image is negligable, and definately not noticeable when playing, maybe if you really take the time to admire the scenary, but who does that when fighting monsters??Lwood - Wednesday, October 13, 2004 - link
According to an article over at LinuxHardware.org, the Linux build of Doom 3 is currently less optimized than the Windows build.Most notably SSE2 code is missing (but will be added later) and GCC does not optimize as good as VC.net.

I guess we can expect the gap to get smaller in later Doom 3 builds, but not to disappear entirely.

Kris, odd, I swear that I was only getting 2 graphs per page when I read the article. I don't know if Firefox is bugging out on me or what.reljam - Wednesday, October 13, 2004 - link
Kris, please put Windows and Linux numbers on the same graph, you know that people will want to see how they stack up against each other.Not clear on why you wouldn't want to do that.

Neither NV nor id has much of a reason to optimize heavily for linux, and it's entirely unsurprising that the windows version performs better. Nevertheless, I expect that the gap will close considerably as the Doom 3 engine matures.Myrandex - Wednesday, October 13, 2004 - link
The AA pictures won't work for me. When I click on them, I get a new window w/ the alert 'hold your mouse over the picture' and then the page doesn't load. When I hold my mouse over the original image, nothing happens. Also, the black pictures to the right of those are way to black to tell a thing about them. Interesting article though. I wonder if 16X AA would be playable in a lower resolution.Jason

That bit about the 16x AA you can enable in Linux is surely interesting. Maybe you can try this on a less performance-demanding game than Doom 3.I'd love to see UT 2004 and Enemy Territory benchmarks for this mode... :-)
