In the past[s5],i seemed to have a decent fps,however,even after a reformat,latest video drivers,the fps just isn't cutting it.I have a P4 3gig processor,1gig ram,x800gto pci-x card.Now i just did some testing.Sitting on pitstraight with 19 cars on track,45fps.I alt tabbed out,checked cpu usage[40%],memory usage [740mb],gpu and environment temps[60degrees],plenty of video memory available.Resolution set at 1024x768.I can't for the life of me figure out why the fps is so low,video card the bottleneck?Any ideas people.With rfactor i get really good fps.

I turned off AA and got a significant increase in fps. I'm running a crappy old X1300 but I'm able to get good fps at 1280x1024 with all video settings maxed without AA.

No AA or AF and at moment i'm in dx7.

Barry what are you doing in DX7, perhaps the upgraded DX will help, I have had some issues but my usually relates to "heat" causing polygons on screen. With the equip you have you should not have a FPS problem, I get 70- 90 on avg. I might recommend reducing detail for "Other cars" down a notch, and some of the in game effects also.

How about your shadow settings? That can be a big fps hit. I agree with Gregg, sounds like your system should be able to handle it, just have to figure out what setting is holding you back.

Download and install Coobits (Nvidia based cards only).

It will allow you to over clock (though I dont recommend that) but more importantly you can change your "max frames to render ahead" from it's default of 3 to a 0. This is a huge FPS improvement. 25% in my case

I have special effects turned of,shadows low.I seem to have most of my problems when running the biturbo,any other car and i pick up some frames.

Go here, read this:

Essential .PLR file tweaks for optimum FPS in GTR2

Some very good tips there -- I've got an X800XT, and these tweaks help quite a bit on my system. Make sure you read through the entire thread.

With many cars around GTR2 usually is cpu limited. I'm pretty sure that's the case here.

Tim - Coolbits only seems to have worked with previous nvidia drivers. Now they have a ridiculous nvidia control panel that doesn't allow as much manipulation :/

If anyone WAS interested in overclocking (see Tim's disclaimer above) you can use the ATITool. It works for both ATI and nvidia cards. If I knew how to link it I would, but just Google ATI Tool and you can find plenty of places to d/l it.

My guess is the DX7 is not up to the task. You never said why you were using it, but I think switching to DX9 will make all the difference as this is what the game was designed for.

Good luck.
