Rfactor graphics performance

Low rFactor frame rates traced to Cool'n'Quiet

A user with a strong Athlon 64 system reported only 15 to 30 fps in rFactor. Another found the cause in AMD's Cool'n'Quiet power-saving feature, which varied CPU speed; others confirmed it could also disturb GPL and NR2003 timing and online play. Disabling it for gaming was the consensus.

I just bought Rfactor and I love the game - My only issue is that the frame rates are pretty lousy. What kind of frame rates are you guys getting and with what equipment? I am getting from between 15 and 30 fps at 800X600 with the following system Athlon 64 4000 Nvidia 6800 GT 2 gig Corsair ram Asus SLI deluxe mainboard win xp Hardly anything running in the background Thanks people!

I had similar frame rates with a slightly lesser system (A64/3200). Tryed for months to get a decent frame rate. Turned out the culprit was the Cool'n'Quiet utility that comes with the ASUS motherboard setup package. You have to turn it off in the BIOS. Frame rate went from the high teens -mid 20's to 100-120 fps. huge difference Dave Erb "Whoever" <no one> wrote in message news:[email hidden]...

This seems way too low. What AA & AF settings are you running with your graphics card? rFactor frame rates are generally pretty good especially compared with GT Legends. Something isn't right! Cheers Tony
I have an almost identical system and am getting 35 (full grid, online) to 60. This is with almost everything maxed. Do you have Vertical Sync on?

Speeding up and slowing down is fairly common these days. By using Vsync you are capping your framerate. I imagine that a fairly high refresh rate would impact the fps as well. My framerates vary, but NEVER do they get down to your max framerate and I've only got a 1st gen XP 64 3000. So I'd say, be brave and turn off vsync and learn to be uncomfortable with the idea of varied fps. (also verify that your frontside bus setting in the bios is at 400 or 800 or whatever the max for your mb is. ) dave henrie

It certainly will cause an overhead and won't be active during game playing. Maybe worth turning on if your PC is on for long periods doing normal stuff like word processing and email or just idle. Then reboot and turn off for games. I was going to say I had seen other reports - then I realised it was Dave on another forum :) Cheers Tony

Thanks Tony. This PC is on almost 24/7. Will try a 3dmark05 with it off though, to see if there's a marked difference. If so, might just have to reboot before gaming :) Deon

Oh there's no doubt that Cool'n'quiet is a good thing sometimes. However why not try it yourself? After all its easy enough to turn on and off and if it is the source of your slowdown it'll be immediatly apparent when you check CTRL + F for the framerate in game. As far as I can tell all CnQ is is a throttling device for your powersupply thats matches PS output to your powerneeds of the moment and switches fans to match heat output. With it off the PC PS cooling fan runs at full speed all the time thus creating somewhat more noise and putting more heat into the room. Mine has been totally reliable since switching it off. BTW I originally got the tip from some thread in either the GTR or rFactor forums in RSC. No idea now which of the thousands that it was but its there if you care to look :) Dave

It has been reported that GPL and Nascar 2002/3 can do weird things if that Cool'n'quiet is enabled. Nascar will drop to 1fps OR will be much too fast OR will just not connect online. Disabling all new'n'cool power saving features in a gaming machine is a good idea. I think it can be done with the Windows control panel power applet, setting the computer to a desktop computer / always on. -- Mika Takala

thats a *very* interesting bit of information that explains a lot of the stuff I used to see when CnQ was enabled. Thanks for this Dave

I heard similar stories about q&q causing some stutters and fps slowdowns on ASUS boards. Remember: the best way to conserve power is to switch your pc off when you're done with gaming. Cheers, uwe -- GPG Fingerprint: 2E 13 20 22 9A 3F 63 7F 67 6F E9 B1 A8 36 A4 61

Definitely something wrong. I've got a similar system, but with a 3500, and I don't have any FR issues unless I put everything on the absolute max. I have one or two things down one notch and it's fine. -Larry "Whoever" <no one> wrote in message news:[email hidden]...

I have proper cooling. I have NO need for something that artificially slows my machine down. I can understand it for some, but I have no need for such things. -Larry "Dave Erb" <[email hidden]> wrote in message news:[email hidden]...

It does that by running components at less than optimal speeds. Less heat generated by IC's, less rpm on moving parts like drives and fans. The way a PC keeps things cool and quiet is to restrict its ability to generate heat. It does so on a needs basis. So that when you're running an intensive process (i.e a game) you're putting more demands on the components in the system causing them to heat up and use more voltage to cope with the processing demand. A processor at 100% utilisation runs significantly hotter than one running at 0% utilisation. A heatsink fan will also then be required to spin at less rpm making it quieter, etc. A real performance killer if cool'n'quiet takes over. -- Cheers, Rod.
