View Full Version : Game lagging and Spiking

12-23-2011, 01:05 AM
I just replaced my Gigabyte 9800GTX video card with an ASUS GTX560Ti video card .... I have played right through Assassins Creed Revelations with the 9800GTX with no problems at all...now with playing with the GTX560Ti (on paper a much better vid card) the game lags and spikes like crazy.. I need help or advice on this problem as I am at a loss to how to fix it. All my drivers, DX etc are all up to date. I run a Intel i5 3.3 cpu on a GA-P55-usb3 board with 8 Gig ram using Win 7 64bit ... I have no problems with any other game including BF3, MW3 Rage etc.. and as I said the game worked perfectly with the 9800GTX.. could it be that the game will not work correctly with directx 11 ....which my new vid card installed when i changed the card ...can I go back to DirectX 9 any ideas please?

The game is DX9 only, they didn't think it was worth implementing suport for DX11 for some reason, and DX 10, though AC 1 supported it, seems to have been completely bypassed.

Thanks Anthony ... I will try and figure out how to get back to Dx9

Nope its not a DX11 problem....Its the card...I replaced the GTX560Ti with my old 9800GTX and all the games run perfectly again.... will have to dig further ito this problem.:/
