300A+viper550+GPL OpenGL=15frames!?!

Is it possible that from an "in car" view ,gpl is reaching only about 15 FPS?From the behind view it gets 36 fps. Even with the mirrors set to show only the cars, it doesn`t get any better.I`m talking about training, without other cars.The graphics are awful compared to the rendition and voodoo2.Does anybody have some different experience?

The OpenGL driver uses a particular call to map the images onto the mirrors, and that call is unoptimized in the TNT drivers. I've already posted two "requests" for a fix at nvidia's website (not that I expect them to oblige, but it would be nice). Check the Core.ini file for a line that reads "mirrors every" - it defaults to 1, but performance will improve if you set it to 4 or 8. It really ruins the mirrors, and this problem is the only reason why I still have my original Monster 3d in my machine. I'd much rather have a A3D sound card to replace my ancient sb16, but I don't have the slots. Rick

With the following in core.ini and using the 0.48 Nvidea reference drivers, I get 36 fps most of the time: [ 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 ; I find mirrorsevery at 4 just being sufficient for online racing. More on this is in the readme that comes with the papy OpenGl patch. Bart Westra

Thanks to both! I`ll try that.

I looked in my "core.ini" file (GPL), I could not find the above lines to alter! Are they sposed to be there already, or do the have to be added? D'oh.... Dave Hawnt (UK-GPL)

You have to add them. There is a sample core.ini in the Opengl.zip file. Regards Bart Westra

Does this work with 3Dfx cards (V2?) or other cards only (TNT?) 8-) *Peter* #:-)

If they aren't there you didn't copy the core.ini from the patch distribution into your gpl directory, or else you copied somebody else's core.ini over it for online racing, perhaps? rob. >> With the following in core.ini and using the 0.48 Nvidea reference drivers,

There is no need to use opengl with 3dfx cards. You can use the 3dfx acceleration of GPL with them. The core.ini statements above are specifically for Opengl acceleration. They are a workaround to optimize a call to Opengl that is used by gpl to draw the image in the mirrors. This call is not handled efficiently by the TNT drivers. The workaround minimizes the number of calls made. Bart Westra

I meant does this entry in the core.ini file (specifically the entries relating to the mirror refresh) help speed up graphics and improve fps when using a 3Dfx card, or *only* for Opengl stuff? Which your statement below now answers, thanks anyway. 8-) *Peter* #:-)

% I meant does this entry in the core.ini file (specifically the entries % relating to the mirror refresh) help speed up graphics and improve fps % when using a 3Dfx card, or *only* for Opengl stuff? However, one can speed up their fps with 3dfx cards by using the glide-wrapper found at http://www.grandprix2.com/gpl/patches/glide2x_253.zip One can set the mirrors to refresh at different rates and will thus improve frame rate. -- **************************** Michael E.

Thanks for the info Michael. Do you think its worth it though? Voodoo2 on a 17" monitor at 800 x 600 on an Abit bx6 m/b and get 36fps on GPL with most options on, (during offline use). However, I tend to turn the graphics down a tad for *on-line* racing and pretty much maintain 36fps for most of the time here too. So would there be any real benefit in using the wrapper for me? 8-) *Peter* #:-)

It would more than likely allow you to be online with more detail turned on or even run at the next higher resolution. The wrapper is easy to use and easy to uninstall. There are a couple of tracks in GPL that really seem to suck frame rates at some of the turns. Even dropping from 36fps to 32fps can rob you of some prescious 1/10's of a second due to car control degradation. I think it's worth a go, just to see for yourself. -- **************************** Michael E.
