I've recently bought HD 7750 1gb ddr5.
I'm suffering fps drops every now and then in every game please I need help..
I've played Crysis 2, Fifa 12 and Sandreas uptill now and I am getting fps drops every 5 secs..
On my 9400gt I've never felt this..

Thanks Gearbox.
I think my the reason behind this fps drops is my PSU.
But lets see if this update fix anything if it doesn't I have to change my PSU.
Can you guys suggest me a cheapest possible PSU which can handle HD 7750 good.

@OP: Why dont you supply your rig config? makes the helping task easier, plus its in the forum guide.

incorporate it into your signature for easy access by members.

FPS drop can occue due to cpu overheating as well . so make sure cpu is not overheting.

you are using a 1.6Ghz proc with a 800mhz 128bit gfx card? with ddr2 667mhz ram? thats bottlenecked IMO.

you should change your psu, mobo and proc immediately. or stop using the hd7750.

though the cpu speed is less the PSU and the cpu should cope up with the gfx card .. come-on GTA SA shan't lag .. my educated guess is cpu overheating ( idle cpu temp of 50c is too much and the load temp should be below 68c ) ) is what causing this issue .. so op better remount the cpu heatsink using some good TiM or better buy a new cpu cooler.

My 9400gt used to play GTA SAN andreas pretty good.
And I have also played GTA 4 with 9400gt at 17fps..

did you use any fps measuring tool?

and 17 fps is WAY too laggy. personally, i try to reach 30fps in games which are too heavy for my rig. reason? the same reason why movies have ~24fps. i'll leave it for you to figure it out. ;)

17fps is quite good for 9400gt tbh(Medium settings with 720p resolution).
Your rig is better than mine apart from your graphics card.Especially your processor is 10x better than mine,

which is why i sacrifice on resolution. i still have my CRT monitor and play on 1024x768 res. :p reduces the load on my gfx card by a helluva lot.

Batman AC gave ~24 fps on medium setting and no physx. couldnt play it due to lag.
