Solved

Just switched graphic cards from a Radeon HD6870 to Diamond HD7770, now having significant fps droppage

Most notably: While gaming FFXIV: a realm reborn on the HD6870 I could play on maximum settings with a 30 fps average. Now, playing with the Diamond HD7770 I get 8 fps on maximum. Unplayable. Even worse, I put the graphics down to low and I only get 12 fps.

I thought this must be a driver issue, so I have updated all the drivers. I even disabled my on-board video card. Still no difference. In the in-game graphic settings it detects the graphic card as a hd7770, so I'm really confused.

Is this card just absolute crap? So much so that I can't even play any games with it?

My computer specs are as follows:
Windows 7 64 bit
Core i3 -2200, 3.1 ghz
4gb ddr3 ram corsair
600 watt psu
5000gb 7200rpm


HELP PLEASE!!! I HAVE TO GAME NOWWWW

    The 7770 is only about the 50% of a 6870, you make a severe downgrade of the Gpu

    You downgraded your GPU, try dropping the settings.

    the 7770 is a step down in gpu power... the 6870 is pretty close in performance to a 7790 or 7850... so you downgraded your gpu pretty badly.

    that said i am having issues buying the drop would be that bad. considering i'm able to play pretty much any title on high with my 7770... unless FFXIV is just that badly coded (which is possible).

    don't know what to tell you, i'd try a clean install of your graphic drivers, and an update of your mb bios. see if that can't squeeze a bit more performance out of your gpu. but yes... you'll see a hit in performance going from a 6870 to a 7770
