Ok so I have made a new thread because its now a different card and involves every game I play.
So the problem I have is the same as with the evga 780. I now have a Asus 780 ti as I thought the evga must have been a faulty card.
The performance I am getting from the 780 ti is sub par to all the benchmark tests I have seen online. With Arkham asylum I am getting fps ranging from 50+ to high 20s/ low 30s. When i turn off DX11 the fps improves greatly but in benchmark the game still dropped into mid 30s at times. There is also crackling sound and slowdown when the intro titles are loading. With crysis 3 I am getting anywhere from high 50s to mid 20s in larger areas. The change in fps is very noticeable.
My specs again are -
Intel core i7-2600k @3.4ghz
16gb Kingston hyper x 1600 ram
Asus gtx 780 ti directCU II OC 3gb
corsair TX 750 psu
Sabertooth P67 motherboard
The Card drivers are defiantly up to date. I have installed them manually. Ive had Geforce experience install them, and I have installed them off the cd (separate installs). I have verified all driver certificates and my Direct X is up to date. I have updated the P67 motherboard drivers and verified the integrity of the game cache for Arkham city.
Where do I go from here! with these cards I was fully expecting a case of plug in and play at maximum graphics at an almost constant 60fps
