FEAR breaking my drivers?

Didn't know how to phrase the title, so my apologies in advance.

Got a bit of a problem.

When playing fear, if I turn VSync off, I get from 27-110FPS (fluctuates wildly) depending on what's onscreen, with the usual being 55-65FPS (I'm on a LCD, so obviously not all display, but that's what they're being processed at).

Thing is, after a random amount of time (30 seconds to ten minutes), it seems like my GPU's downclocking as my frame rate becomes a steady 28-32FPS.

With VSync on, it's from 30-60FPS usually, but the same thing happens after a short while.

FEAR seems to break even the most conservative overclock on my machine within ten seconds, so I've been using stock clocks. Anyone ever come across this before?

I'm running the 177.79 drivers with modified inf.

 

yes with mu old hp i had a 8600m gs and i overclocked it. it ran fine for about 20minutes that artifacts, driver failure everything. i think fear is one of the best games to test your system stabilily.

 

So what, I may have to underclock to get decent stability?

Or should I try a newer set of drivers? (Up until now I was loving the 177.79s, so I saw no reason to change them lol)

 

Is it happening to you everywhere in the game or in a specific part? For me it was only in the mission 'Bishop', before and after that mission I had no problems.

 

I think you are having the USB driver problem that has hurt a bunch of us with FEAR. Performance will be totally fine, and then drop off after a few minutes to 10 minutes or so, and stay that way until you exit and restart.

It has been tied to Logitech drivers, but I have the same issue with my Tablet and a Walcom driver, so it varies.

But yes, it seems that the GPU is taking a crap, but it's actually a bug with USB drivers. Googling it, here's the first hit, and there are many more. Some have had success fixing it, but for me I had to disable my touch screen to do it, and that wasn't worth it to me. Check this out:

well i found that on my g5 mouse that if i would change the DPI on it the game would stutter for a second and then the frames per second would go back to normal. and with my vx nano i would just unplug it and plug it back in when i notice it happening. seems to be a usb problem for me as well but i figured its cause imo fear is a poorly optimized game and runs like crap on even top notch systems. but on the other hand they made a huge improvment with the second one using the crysis engine. at least i think they did.

 

Ok, did a little experimenting, and it only happens in the original, (maybe EP, haven't had time to check), NOT on Perseus Mandate... Which is weird because I'd have figured they used the same engine?

(I'm assuming that having the trilogy pack with PM would have brought the original FEAR's patch up to date?)

@be77 Cheers, I'll check that out.

@imhungry I'll try just resetting the mouse, cheers, but I can't agree with you on the poorly optimised bit... It runs great on all max setting except AA on my system, which as you can see isn't exactly powerful.
