Negative performance increase with GPU upgrade

post #1 of 2
Thread Starter 
Hello OCN.


So a few days ago I got my Gigabyte GTX 560 TI OC edition (Windforce cooler) that was clocked to 900 Mhz instead of the standard 822, and I later overclocked it to 990/2250. However even through it folds really well compared to my old Sapphire Radeon HD 5770 clocked @ 930 from standard 850 on core and 1300 instead of 1200 on the memory, it seems to decrease performance in games such as DiRT 3, Crysis and Crysis Warhead. There're also some games it perform better in, such as BF3, BFBC2 and Metro 2033.

However it just seems really strange when it should be much better overall out from those benchmarks I seen. Anyone got any explanation on this? Anything in the nVidia control panel to do or something?

Also note that my drivers on my HD 5770 were dead and therefore it had even slightly worse performance at the end.

Appreciate any input:)

It could be a driver issue you are having. Did you just uninstall the AMD drivers and install then Nvidia drivers or do a driver clean in safemode or reformat?

 

Boot into safemode by pressing F8 at windows startup. Uninstall Nvidia and ATi drivers (if applicable), grab a program named Driver Sweeper (grab it here: http://www.guru3d.com/category/driversweeper/), clean all Nvidia and ATi drivers, restart back to normal mode and install the lastest Nvidia drivers.

.

Driver conflicts can cause stability and performance issues so it will be worth giving this a shot. Hope it helps :)
