Lag (Unidentified Cause): Help?

[v0rtic3s]

Quick question: can heat ever, in any case, cause lag on a GPU?

I've never lagged in F.E.A.R., for example, but I just changed from a massive Thermalright sink with a fan, back to the Zalman 9700 (used to run), and my temps actually went back up (idle @ approx. 50, load @ 80+!) on my x1900xtx.

The only other thing I did on my system today was install the ATi CCC again to check something, which didn't totally install properly, or uninstall properly, though it's not showing in my system... but if I click the shortcut, it launches.

Stupid Windows install error of "couldn't write to key "\software\Microsoft\Windows
CurrentVersion\Run" which I have no idea what that means. Got a similar error trying to install Nero a while back.

Something up with my system, I guess... though no one can tell me what's wrong that I would get that error.

Anyway... I'm now getting lag I did not have until today, after these two issues, so one of these things would seem to be the culprit.

Any ideas???

I'm not sure if your GPU is downclocking itself, but your CPU might be if it is also getting too hot.

Hey i bet its ATI CCC ! Can you roll back your Os to before it was messed Up! System Restore Point .Oh almost forgot ,Yes heat can cause slow or unstable game play.

Yes it can. However, video cards run pretty hot so 80 isn't that bad.

I believe it says that the program could not write to the registry. The registry is one of the fundamentals of the computer, so if that gets screwed up, your computer can easily be screwed up.

So, my guess the install got borked and messed up the registry which is messing up your computer.

You can try to download CrapCleaner and see if cleaning the registry fixes the problem. Or any other Registry cleaner/fixer should(hopefully) solve the problem.

it means that the software (in this case CCC and Nero) trying to place item(s) / executeable(s) in your windows start up (usually appear on msconfig.msc and since it stored in the windows registry key, you should be able to find it with regedit) so it will start/load automatically everytime windows start up.
i guess you're receiving this message because it fails to do so, maybe the registry key is locked or missing(!).
