I've replaced my broken videocard Asus 9800GT Top with the following card: Sapphire HD7770 OC Edition. I switched the cards and then afterwards I removed the nvidia drivers (in the configuration screen) and installed the latest drivers for my new card. Everything looked ok, but when i play Modern Warfare 3 for example, I notice that it doesn't run as smooth as with my Asus 9800GT, even when i reduce the advanced video settings.
What can be the cause or what can I do to fix this problem? I was thinking to format my pc, but i'm afraid that the problem won't be solved. Can there be a conflict with my old Nvidia drivers? Is my system to weak for the HD7770 card (PCI-e 3.0)? Or is the 9800GT a better card (=256 bit)? Can there be a conflict with my motherboard? ....
If someone can give me some solutions or answers...
I think it's a severe case of driver conflict then. I'd strongly suggest reinstalling windows.
I read a lot of things of driver conflicts when replacing a videocard from another type (AMD - Nvidia). But i find it odd that my "normal" activities on the pc such as Office, internet, mail, Photoshop,... runs smooth with the new card and when i play games the framerate is very poor.
Well, other activities you described don't really use a graphics card .
True. So you think my CPU isn't the bottleneck for the new videocard?
Thanks for the reactions !
If you had a bottleneck, you'd at least see the same performance. Bottleneck doesn't reduce performance, just limits how hard you can go.
Of course, you can always check the CPU usage: but beware, high CPU usage might mean driver conflict as well.
Thanks, i'm going to do some tests when i get home. I hope that my problem is a driver issue and that it can be solved when i format my pc (= final solution).
i got same problem except that i had no past Discrete Cards
