(GPL) Mirror refresh rate?

I seen a post on this NG about setting the mirror refresh rate. I tried to download the file but the server couldn't find it. Now that I want to try to download it again, I can't find that message. Question, Is there a way to set the refresh rate for the mirrors? And where is the URL that tells about it and or the file to download.

The following is only for the OpenGl driver. More info and download at www.papy.com Bart Westra [ Int Profile Values ] value0 = OpenGL:TossHighestMip:0 ; do not change value1 = OpenGL:MipFiltering:0 ; do not change value2 = OpenGL:MirrorsEvery:0 ; do not change [ OpenGL ] TossHighestMip = 0 ; MipFiltering = 4 ; MirrorsEvery = 4 ;

If you have a 3Dfx Voodoo1/2 or Banshee card: At the Fast Lane http://www.grandprix2.com/gpl/patches.htm there's a Banshee patch that also works for Voodoo cards. It's a glide2x.dll wrapper (put in the gpl directory) that intercepts Glide calls from GPL and passes these through to the real glide2x.dll (in the windows\system directory) with some modifications. It's primary purpose is to fix a texture problem with Banshee cards, but it also includes the ability to set the mirror refresh rate in a glide.ini file. I did some benchmarks and found that by setting the mirrors to refresh once every two frames, I can get the same framerates at 1024x768 as I had at 800x600 before. Also, at once every two frames, the mirrors are still good enough for safe online racing. On a PII 450, 128MB, 12M Voodoo2, at startline at Spa, starting last, modern F1 style staggered grid, all graphic detail on except for cars only in mirrors and detail bias set to 25%: (startline FPS / lowest FPS after start / inline racing FPS) Before mirror refresh every 2 frames 800x600 30 / 24 / 36 36 / 28 / 36 960x720 27 / 22 / 30 31 / 25 / 36 1024x768 27 / 22 / 29 30 / 24 / 36 Brian

Interesting and useful data, Brian! Since I too have a PII-450, I think I might, if I get a chance, duplicate your tests with a Banshee so collectively we might be able to compare the two boards/patch in a GPL environment. So that I can duplicate your tests, would you give me the following details? I assume you testing against the AI. How many AI drivers were active? From what position on the grid did you make your frame rate observations? What were your sound settings? What kind of sound hardware do you have (this may taint the comparison). I'm thinking that 1024 x 768 with the Voodoo2 requires a SLI setup. Were you running 2 Voodoo2s? How do you have your Voodoo2(s) clocked? Thanks! I'll see if I can produce some equally meaningful numbers for everybody.

Hi Jack, It will be interesting to see your results. Brian >I assume you testing against the AI. How many AI drivers were active? I had a full field of 19 AI drivers. From last position. Note, I was using the modern F1-style, 2 wide staggered grid. With the standard grid, the framerates are quite a bit lower: STANDARD GRID ============== (startline FPS / lowest FPS after start / inline racing FPS) Before mirror refresh every 2 frames 800x600 25 / 21 / 36 28 / 23 / 36 960x720 22 / 18 / 30 25 / 20 / 36 1024x768 21 / 18 / 29 24 / 20 / 36 MODERN F1-STYLE GRID ==================== Before mirror refresh every 2 frames 800x600 30 / 24 / 36 36 / 28 / 36 960x720 27 / 22 / 30 31 / 25 / 36 1024x768 27 / 22 / 29 30 / 24 / 36 The net effect of the revised grids and the mirror refresh rate patch let's 8 sounds - I'm using "soundQuality = 0" in the app.ini file Turtle Beach Montego II OEM (using latest Aureal Vortex 2 drivers) that came with my Dell I only have 1 Voodoo2. Clocked at 98 MHz, using Metabyte Wicked 3D version 3.15 beta drivers (except for 2.53 glide2x.dll in C:\windows\system). I'm using a Voodoo2 fan from 3DfxCOOL. This helps quite a bit - I can run GPL at 100MHz with the fan, where before, it would lockup within seconds without it. However, even with the fan, NR1999 locks up after a few minutes at 100MHz, but is fine at 98.
