4870X2 and framerate fix

[Tamlin]

I installed a new harddrive recently and reinstalled just as well OS. After updating all the drivers and the OS, I noticed something gone wrong with performance. Bonus, I thought, since I like to tinker... ;)

Framerates were dipping down in several games that ran smoothly before. Weird, I thought and then I rememberred an old fix for F.E.A.R.

I installed F.E.A.R just to confirm my suspcions (so I could report my findings later). Turns out that F.E.A.R ran like it had a 30FPS cap and so I looked for the solution:

Tried it in several games and now the minimum is great and no dips. Here's Stalker: Shadow of chernobyl:

Frames, Time (ms), Min, Max, Avg
29287, 269268, 77, 180, 108.765

In case people want to try this:
settings: Everything on max @ 1920x1200 res
System in sig (CPU@3400, mem@4-4-4-12, 800, 400FSB
Catalyst 8.12
Benchmarked with Fraps


I made a run from the broker in the beginning, through the village on the road and used the road to the house where first assigment is. There I turned and ran back again.

Perhaps others have same issues, so I wanted to post it here. :)

I remember you had to do the same thing for Saitek Eclipse keyboards for Kane and Lynch when that was released. It would freeze every few seconds otherwise.

Odd stuff!

Thanks for sharing, I just bought a Logitech MX5500 keyboard and there's no performance issue so far (nothing starting with HIDVid_046d&Pid_c041& either BTW), but should FEAR be sluggish next time I install it, this trick may save me a headache ;)

NP. Less headache for more people! :D

I disabled several of those human interface drivers and system seems stable. Stalker had dips though running with high framerates at times, same for fallout 3 when I installed it. This solved the issues for several games at once that worked well before the reinstall.

I do have a logitech G5 mouse and a Logitech Dinovo Edge keyboard, but I don't think its for logitech alone this error (as eZ experienced with Saitek).

This is one of the things people often don't think about checking or don't know about, but it seems worthy as a checkpoint at least when getting framerate dips or low framerate in games one should have decent FPS.

Merry christmas btw! :cheers (Or happy turing of the sun for those who don't celebrate christmas).
