Well, i recently installed a new motherboard and since then i have been geting some frame drops.
It goes from 60 to 30 and then back to 60.
With the motherboard i used before i could play Crysis 2 at medium settings with no framerate drops at all, but now i can't play cause it does it so much.
I have an sapphire ATI readeon 5700

This is very strange the problems i could imagin are:
1- Have you installed all your motherboard drivers correctly? also check video card drivers, reinstall them again, could also be, old video drivers were having more frames on that specific game.

2- Does that motherboard have also a pci-e 2.0 16x? it would be possible to have a little performance drop if your gpu is connected on a x4 slot

but i bet on video drivers outdated.

1. I have installed all the motherboard drivers i got with it.

2. Everything is hooked up correctly, and yes. I have one pci-e.

The motherboard is an ASRock 960GM-GS3

I have the latest drivers for my card

What about the GPU driver, have you upgraded your gpu and installed last catalyst version? AFTER the new mobo?

Check if V-Sync is on also. That limits your framerates to 60 fps.

How do i check what gpu i have?

V-sync will output your screens at either 30 or 60 fps depending on whether your gpu produces over or under 60 screens in a second. Try turning it off and monitoring frames.

I could be mistaken and this could be caused by something else, but changing the V-sync setting is an easy test.

I have changed my V-sync settings, it only helped slightly.

Now it drops to 35 and then back to 60!

Vsync do that. Activating V-SYNC when framerate is under 60 it goes straigh to half, (30fps) ,so it is not a good option activating it if you are having FPS flutuation.

GPU = Graphics Processing Using = Graphics Card = Video Card. have you download latest driver version + catalyst control center? that helps a lot the framerate. maybe you had it installed before and now it is not correctly installed:

Btw what resolution are you outputting your video signal? This would also help a lot too.

I'm often in 1280x960 or 1280x720

And yes, I have the latest cataclyst and drivers.

Also, I have 4 gigabytes of ram, Using Windows 7 Ultimate 32 bit and i have an AMD Phenom II X4 955 processor.

does this happens with other games too? if it is just that one it is a game problem, some games are heavy even on low graphics.

check your temps, could be overheat.
April 28, 2012 2:08:45 PM

That happens in all the games i play. Here are some: League of Legends, Risen, Running with Rifles ,Battlefield 2 and Minecraft

I did a stress test a while ago, never got over 65 degrees.
