D3D stutters in UT

feedback · Jun 7, 2002, 05:41 AM

This only happens with vsync on- it appears like the games skips like 5 frames, it happens randomly, and only in UT. It doesn't happen in OpenGL. Turning usevideomemoryVB on gets rid of the stutters, but halves my framerates. Turning mipmapping on makes them worse, as does tripple buffering. The only thing that I've found that works outside of vsync and videomemoryVB (not an option for me) is turning on AGP textures. This just about gets rid of them, but it gives me a little slower performance. What the hell is with these settings? I'm using the Omega/Cyborg 6071 based drivers and windows 2000. I'm running on a laptop with a radeon mobility.

Use OpenGL with the latest render found at http://unreal.epicgames.com

Much faster than D3D and better looking thanks to S3TC textures

In openGL, I get terrible performance all around. Furthermore, my framerate will drop substancially after a few minutes of play, like it's experiancing the high poly bug. It goes back up to full speed after I flush the engine caches only. Also, my frp drops by 20 when I use the pulse gun. No reason. So d3d is twice as fast, and playable, that's why I use it.

Thats wierd - OpenGL is about x3 faster than D3D on my rig - and thats using S3TC textures too boot!

Which drivers and which OS are you running?

feedback · Jun 7, 2002, 08:58 PM

Using 5093's, and Win2k. The problem existed in XP also.

Try the following UT OpenGL settings in your UnrealTournament.ini file - overwrite the old section completly

[OpenGLDrv.OpenGLRenderDevice]
RefreshRate=0 // Set the highest refresh rate that ur monitor will be able to handle depending on ur given resolution.
DetailTextures=1 // I recommend setting this to "false" if u have set ur "lodbias" at -2 (it's maximum setting). The graphics quality increase isn't going to be noticeable if "lodbias" is already at that setting. I recommend setting this to "false" unless ur system can handle 'both' "lodbias" and this setting enabled/at max setting.
UseTrilinear=0 // I recommend disabling this ("false") unless u are not having any fps problems enabling this. Graphics increase isn't worth the fps drop IMO.
UseS3TC=1 // If ur using an card that can do S3TC, set this to "true". Otherwise set this to "false"
UseTNT=0 // If ur using a TNT card or want to force your card to use only TNT features, set this to "true"
LODBias=-2 // Values range from -2 to 2. The lower the value, the better ur textures will look at the cost of performance. This is the line that fixes the lameness of UT's graphics when using the opengl raster.
UseMultiTexture=1 // Set to "true" for better performance.
UsePalette=1 // Set to "true" for better performance with no noticeable loss in graphics quality.
UseAlphaPalette=1 // Set to "true" for better performance with no noticeable loss in graphics quality.
Translucency=1 // Enables transulcent (c thru) textures
VolumetricLighting=1 // This will enable or disable the fog effects on some maps. Few maps support this effect, so I recommend enabling this ("true") unless ur having problems on maps with fog effects.
ShinySurfaces=1 // For levels with shiny surfaces or reflective surfaces. Few maps support this effect, so I recommend enabling this ("true") unless ur having problems on maps with shiny surfaces.
Coronas=0 // This is for extra lighting or glare effect on light sources. Fps isn't much affected when this setting is enabled but at the same time it isn't noticeable even if it is disabled. Check it out urself and take ur pick.
HighDetailActors=1 // Set to "true" for better looking transparency effect for players with power-ups. Disable ("false") for better performance but ugly looking players with power-ups.
MaxAnisotropy=16 // This setting controls anisotropic filtering. Set x to 2 with an nVidia GeForce (1/2) graphics card & 16 with an ATI Radeon to enable anisotropic filtering for improved image quality. Although currently this setting has no effect (Apparently). Leave x set to 0 to disable anisotropic filtering for improved performance, or if your graphics card doesn't support it.
AlwaysMipmap=1 // Set this to "true" if u want to enable mipmapping method for a slight increase in graphics quality. Disable ("false") for better performance.
UsePrecache=0 // Set to "true" for faster loading. "False" if ur experiencing lock-ups or crashes during the caching state.
SupportsLazyTextures=1 // Leave x set to 1, as this should reduce memory overhead.
UseVSync=0 // Syncs to screen or not
DisableSpecialDT=0 // Not sure what this setting does, but my fps didn't change even if this setting is enabled or disabled. I recommend setting this at its default "false"
UseFilterSGIS=1 // This will help improve the multitexturing quality (if multitexturing is enabled). Enable for a slight graphics quality improvement with no noticeable slowdown on performance.
Use4444Textures=0 // This is for those folks who are playing at 16bit. This could increase ur fps a bit if enabled ("true"). Set this to "false" if ur playing at 32bit.
UseVertexSpecular=1 // Not sure about this one, but my guess is that enabling this will help increase ur fps.
UseGammaExtension=0 // Set x to 1 & make any gamma adjustments before loading Unreal Tournament. Leave it set to 0 if you have no such issues.
UseModulatedGamma=0 // Setting x to 1 will modulate a white texture on top of everything once the scene is rendered. This can improve game brightness but will make textures appear washed out & reduce performance. Set it to 0 at all times unless you are desperate for an increase in brightness.
MinDepthBits=32 // sets the colour depth bits per pixel. Valid values are 16 or 32. Selecting 32 (If your video card supports it) will give best image quality, but slowest performance. Try setting x to 32 should you experience strange graphical issues.
MaxLogUOverV=8
MaxLogVOverU=8
ShareLists=1

I'm assuming u mean the 6093's - I'm still using the 6071's as I havent had time to download 20megs yet.

Thanks, I'll try those settings, but it seems to happen no matter what ini settings i use.

feedback · Jun 10, 2002, 03:55 AM

It seems to have improved- my average in UTbench with vsync locked at 60hz is ~48fps in D3D and OpenGL. Plus the slowdown after periods of play seems to now be minimal. (only 4 fps at max gained when flushed)

Why are you running VSync locked? UT is one of the few games where I deliberated unlock VSync in the game settings as the game just will not tear no-matter what graphics card I've been running

I'm running on a laptop with a 60 hz refresh rate. The game gets tearing beyond 60 fps, so I need to vsync it for it to look smooth.
