Video card settings for maximum FPS

[Opferlamm]

Hi, could anybody please post the correct settings for nVidia video cards to reach a maximum of FPS in nexuiz? For nexuiz using OpenGL i am not sure, whether my settings are correct or not.


Antialiasing settings: OFF
Anisotropic filtering: OFF
Image settings: High performance
Color profile: Not available
Vertical sync: OFF
Force mipmaps: None
Conformant texture clamp: ON
Extension limit: OFF
Hardware acceleration: Single display mode
Trilinear optimization: ON
Anisotropic mip filter optimization: ON
Anisotropic sample optimization: ON
Nagative LOD bias: Allow


And if somebody is using the rivatuner for more settings, could you please post the setting you suggest for bringing more FPS to nexuiz?

I use a FX 5200 with DHzer0point 0.7803 driver.
1.1 GHz Celeron
512 MB SDRAM

Vertical sync: OFF

Yes, that would allow you to get the highest frame rate but only in the signal cable. It will be useless as the screen will not be able to refresh quick enough to disable every frame. Since your card supports triple buffering you should enable vertical sync except when bench marking.

By the driver name I guess you're using Windows. Which version? You are probably better off trying to improve performance at a lower level as drivers won't get you much further, particularly as you are more likely to have a CPU bottleneck than a GPU bottleneck. Find a BIOS tweaking guide (Toms Hardware Guide had oen a while ago) and run through all of the settings optimising. Then go through your OS, then go through the drivers.

This is assuming of course that you've already set all of the minimal settings in Nexuiz.

You are right. I forgot to mention some things:)

OS is XP Pro with SP1. Nexuiz is on the lowest possible settings. BIOS is optimized but i had to update it and i am not sure, if i am able to do it or not. I frighened of terminating my PC Cause of this, i am not able to activate "fast write".

To optimize my OS i used tweak XP, a registry cleaner and sysoft sandra.

If i use vsync in combination with tripple buffering, the players seem to "blink" over the screen, in one frame i can see them and in the next not. So i turned vsync and tripple buffering off.

Sorry that i forgot to mention this.

You would get more improvement by compiling your own DarkPlaces engine optimized for your processor, this can be done with Microsoft Visual C++ (any version, more recent is preferable, as long as it has the good optimizing compiler installed) or DevC++ or MinGW.

I would cross-compile these for inclusion with Nexuiz releases but my cross-compiler is gcc 2.95.3 which is too old for many modern cpu features.

I have seen 40% speed gains from compiling for amd64 32bit (not native 64bit) vs the default compile of 686, compared to 50% speed gains over 686 from compiling for native amd64, you should be able to get at least 30% more performance on that Celeron with a recompile.

Or perhaps Willis could do a recompile and post it here?

P.S. speed gains of 20% have been reported with the latest engine beta, so things should improve further in nexuiz 1.6.

Update: I just benchmarked lots of different cpu optimizations and found that after the optimizations for nexuiz 1.6 the engine is no longer cpu limited on my Athlon 64 3200+, so I can't find any speed difference with any combination of cpu optimizations, this should be good news for everyone (CPU being a lot less important now).

I am not able to take the correct values for my video card and i'm really unable to compile anything. Even the word "compile" i have to search at wikipedia

But thanks for your posting. So i wait for the 1.6 version. Counting the days left till 31.5
