AvengerUK Posted December 7, 2011 Share Posted December 7, 2011 Hey all, I keep seeing conflicted reports of CFX usage in skyrim - (that is, reports of it working and some not) Anyway, long story short: I'm on a clean install of W7 x64 and on 11.11c + CAP2 drivers, and vanilla skyrim (i.e. nothing modded). I havnt played the game at all since release (dispite having it) as had terrible performance (negative scaling). It would seem 11.11c are the same as the last 3/4 drivers released, that is: Crossfire doesent work and hasnt been improved. Throughout the last releases, my CFX @ 1680x1050 gives me vairied FPS, <30FPS with highs of 50 or so, with GPU usage 1 & 2 @ ~40% each. Windowed mode (no crossfire) is much smoother, and runs 90 something % usage. What really confuses me is why some people report CFX working, and some not. Anyway, cutting to the chase, is there anything else I can try? (alt-tabbing gives no difference) - as I really would like to play, but, smoothly...

jhazor Posted December 7, 2011 Share Posted December 7, 2011 i get a wierd situation where with 11.11c my skyrim seems to ignore Vsync and caps at 120fps but on it's lowest points of fps it bottoms out at the Exact same FPS as a single card i can pretty much sum this up as i don't know what the hell is happening Link to comment Share on other sites More sharing options...
AvengerUK Posted December 13, 2011 Author Share Posted December 13, 2011 Just a little update... I decided to give overclocking my i7 a whirl, and managed to try skyrim. (I say try, as on a prime95 the temps hit 80 & Bluescreened @ 4.8Ghz, however that was with the motherboards auto-oc, which proberbly wasnt a good idea...Ive actually no idea what acceptable temps for a i7 2600k are >.<) Anyway, on skyrim the overclocked CPU did help quite a bit, GPU usage on both around 60% - FPS @ 1080p around 50 to 60 FPS with full AA, AF. Atleast its an improvement...however, without the OC'd cpu its still @ 40% per GPU and negative scaling. Quote:(@CatalystCreator) Skyrim CF is support in 11.11c - but title can be CPU bound in certain cases, so that's why CF scaling is not always apparentan i7 2600k shouldnt need to be overclocked to such a level for crossfire to scale I'm close to just getting a 360 copy, cant be arsed to overclock just for the one game. Edit: (On 12.1 preview drivers now) Link to comment Share on other sites More sharing options...
myounage Posted December 14, 2011 Share Posted December 14, 2011 Some users that have CFX working with good scaling and 60fps outdoors are using CPUs MUCH less powerful than a stock 2500k/2600k. You shouldn't have to OC. People are running Phenom IIs (significantly less powerful than i7 920) with very light or no OC and getting 60fps. I only gained 3-4 FPS out of pushing my i7 to 3.4GHZ from 2.66GHZ. Don't believe ATI. Link to comment Share on other sites More sharing options...
