Here's some info on my pc setup:
Motherboard : G1.Assassin killer Gigabyte
Processor: Intel Core I-7 960 @ 3.2Ghz
VGA: Single Sapphire HD6990 ATI (not over clocked or anything)
Rams : 12GB Corsair
Hard disk: 120GB SSD Kingston and x2 1TB Western black
Also am on win 7 64-bit, Not sure if this would matter but i have UAC off and AVG Firewall disabled.
Screen Resolution 1920x1080
so anyways, if my config is set to Ultra and Resolution is 1920x1080 full screen Vsync off, i'd be somewhere around 15~20 FPS most of the time. so am running it on medium atm just to enjoy playing w/o fps issues.
I tried latest Catalyst which is 11.11, but same results, so i installed "AMD Driver Nov 3 smooth Battlefield 3 gameplay Driver from marthand" and AMD 11.11 CAP 1.
since its my first ATI card i dont really know much about catalyst and stuff. Here are few things that i've made/Tested so far. I have uninstalled/re installed couple drivers(including Driver sweeper just to make sure everything is gone) 11.10 preview 2/3 and latest 11.11.
I have ran Heaven DX11 Benchmark 2.5,Furmark version 1.7, and i have gotten amazing results with them. This is a link to my Furmark result:
What i have noticed during tests, i've had MSI afterburner running in the background to check on the GPU's usage, on both Heaven and Furmark, they were both hitting 90'ish%, but on BF3 GPU#1 usually around 35ish% and #2 at 0%, so is that normal? and again i only have single card just not to mess things up with you.
I know it's mostly a driver issue but, i know some people who are running same driver with the same card, and they never had any any issues at all.
Its frustrating that i spent last 2days trying to figure out what's the issue but everything seemed fine on tests.. OH and 1 more thing, whenever i'd install drivers, in the end of installation id get a msg saying "installation was finished but some warnings occured" and weird thing is i never saw any error window that would pop during installation, everything seemed fine, i even checked the log files and everything was "success".
So finally, i read on battleload forums, someone saying turning off fullscreen should help a little, so i tried that and actually i noticed difference! i changed resolution to 1600x900 and turned off Fullscreen and switched graphics to Ultra, i was somewhere near 30~40 FPS, although it randomly drops to 15~20, but atleast there's some improvement!
So is there anything that i have missed that could fix my issue? it be greatfull to hear from you guys.
Thanks in advance!
