Hey, I've been testing my new powercolor HD5850 and came across some strange results. I've been using the Company of Heroes tales of valor stress test to see how my new card would perform.
Below are the settings i used and also the results.
E8400@4.4ghz GPU Stock Monitor: 25Hz
1920x1080 All Max 8xAA 1920x1080 All Max No AA 1650x1080 All Max No aa

When I set my TV/Monitor any higher than 25Hz I get some very strange artifacting in game. I'm using a Toshiba Regza 32" TV Max res:1920x1080 Max refresh rate: 60Hz
Does anyone have any idea why im getting so little FPS there seems to be very little differance from max settings to minimum settings which seems odd to me. Upping the refresh rate helped minimum FPS, but the game went very dark and there were a few artifacts : /
P5Q-E P45 Mobo
E8400@ 4ghz 1.208V
4gig of DDR2 1000
PowerColor 5850 775/1100
Coolermaster real power M700
Coolermaster HAF 932
LG sata DVD ROM drive
Maxtor Diamond max sata 2 160GB
Im using driver 8.66 which is the driver recommended by AMD/ATi on there website.
the stupid human eye cant detect more than 30 fps, so 35 and 35 human eye cant see the difference and only from 30 to 60 fps human eye can detect a noticeable change and imo 20 fps enough for me in fps shooters and 30 in thank god!!!!
I thought that refresh rates has something to do with FPS, and from my testing it seems that it does affect it, but only slightly.
I too thought that maybe my E8400 was bottlenecking my 5850 some what, but I tested with the CPU at 4ghz and 4.4ghz and the results didnt change much at all.
But just to make sure i'll put my 5850 in my friends rig, he has a Q6600@3.4ghz so that should get rid of any cpu bottleneck.
I've also noticed that my call of duty waw FPS hasnt changed at all, going from a 4870 512mb to a 5850 just seems to be a cap of 91FPS which is fine obviously but im just curious as to why it hasnt changed/increased.
Thanks jennyh for you input =]
Oh on the subject of CPU bottleneck i did a 3dmark06 test with CPU@4ghz and GPU @ stock and got 18953 points.
Then i upped the core clock and memory of my 5850 to 775/1125 and only got 19068, only 115 more points.
So then i overclocked my CPU to 4.4ghz and got a score of 20762.
Yeah i am very happy with the performance, just curious as to why i get very similar frate rates at 1024x768 everything low vs everything on max at 1920x1080, but like i said i'll wait for some new drivers to come out and then test again.
You shouldn't need to push your CPU higher at all thats already very high. Your CPU deffinitely is not holding you back because I ran the same benchmark with a processor at 2.5GHZ and hit 103 FPS av. or around there With a stock 5850.
Try uninstalling old drivers and see if that helps. go to device manager and It's under display adapter. You will see all your installed drivers. Get rid of all except your 5850.
