Stuttering in games after driver update

i have a sony laptop with an ATI 5650m 1gb.

i've been running catalyst 11.2 for 18 months, and a week ago i decided to update it (for GW2).

i tried different catalyst versions, and i found the mobility 12.3 to be to most suitable.

after i updated the drivers, i started noticing fps stutters/hiccups in all the games i play (skyrim, tf2, tribes ascend, gw1, burnout paradise), not only that, but my anti aliasing messed up, all of the games that had no AA option inherently had some form of AA (felt like FXAA) prior to the 12.3 update, but now they're all jagged and ugly (tribes ascend for example), even flash videos and pictures are jagged.

anyway, back to the stutter; Every 30 seconds or so the frames would slow down (even in less gfx intense areas) for a second, and sometimes freeze for a second or so.

i tried rolling back the drivers but it didn't fix neither the AA nor the stutters.

temperatures are normal, i ran all sorts of tests and maintenance procedures, like cleaning the ventilation ducts, running scans, disk cleanups, defragmentation, driver sweeps, registry cleanups, and driver error checks.

and as far as the catalyst control center goes, everything is application controlled, anti aliasing is set to multisample, Vsync is off, and no tesselation.

nothing worked, and i'm very worried about this issue sticking with me for as long as i have this laptop (over a year more).

Can anyone please give me a hand?, i've been trying to fix this for a week now D; !!

 

bump!!!!!!!!!!!!

 

I would either call GPU throttling (most likely).

Your card might be heating up, check temps, clean out the laptop

or your CPU throttling try ThrottleStop.

 

already mentioned temps are normal.

 

Maybe updating your AMD drivers enabled MLAA?
I tried it and all it did was blur my screen.

 

no it didn't enable MLAA
