Hi, I'm seeing a very strange thing when running offline: whenever I get close to the AI cars (about two to three car's length behind), they start to "lag" (i.e., rapidly jumping back and forth in the track). Normally the "jump legth" is about half a car or a full car's lenght. They "jump" really forth/back really fast, like 2 or 3 times a sec. I've never seen this in any offline game that I've tried so far... anyone else experiencing this? My specs: Intel Q6600@3Ghz, 4Gb RAM, ATI HD5850 1Gb 12.1a Preview drivers, Win7 Home x64, 1920x1080. When playing online this doesn't happen. Detail: if I'm at their side or in front of them, this doesn't happen. Neither it they are well in front of me (more than two or three car's length).
Try this In player.PLR file change the following: Flush Previous Frame="0" to Flush Previous Frame="1" http://isiforums.net/f/showthread.php/2832-A-possible-solution-to-stuttering...... And disable Antialliance to see if it helps and you could also try lower resolution to see if there's any difference.
Thanks, already using this... will try to lower the AA and report (but I'm already using the lowest AA level... if this is the solution, then I'll have to live with the lag, because the jaggies are worst)
Try lowering your resolution, and cutting back on some detail. Put shadows on low or off. Plenty of little things you could do, as you probably know already. Alan
Well, after some testing, I found that the problem is gone, but I'm unsure what was happening. I've lowered everything, and then changed back to what it was before (couple restarts in the middle and at least one online session). Now it's working ok... even some tracks that were really lagging are fine now (offline and online). Dunno what happened. Anyway, thanks to everyone that helped.

Yes I've seen it too, it seems there is a certain combination of settings that causes it. Mine too has gone away for now. Also 5850 with 12.1 drivers
I had this problem myself, but it was during replays. In case it ever develops again there are a few more things you can try. Disabling V-sync (which I see you don't run), setting the Max Pre-Rendered Frames in your forceware to 1 (or 0), and disabling AMD Cool'n'Quiet (Intel SpeedStep for you) in the BIOS is what sorted me out. And that has to be done from within your BIOS if you do in fact have it. Doing from within Windows power management wont disable it.
