Perfomance Issue

[famine 4]

I downloaded the latest ATI drivers 11.6 and some how its forcing Jet Fighters 2 to run in D3D10 (DX10) where as before my game used to run in D3D9. as u can see in my screen grab there in the tob corner..

 

 

Please dont be mislead by the 60FPS in D3D10 it feels as if my game is running at 10FPS ingame... In the menu i am doing D3D9 and getting the perfect 120FPS which is accurate. as if the D3D10 is misleading the game i dont know. I tried other games and I dont have this issue with any them and they all run in D3D9... This is the first time i have seen D3D10 and of course its my favorite game of all games this problem would appear the game i play and love most. typical murphy's law.

 

I tried setting things in my ATI Catalyst i forced everything to manual or in application control still no change. I have undated DirectX and installed some old DirectX massive to add in files that werent there from what i read in the ATI forums.

 

Any ideas? i am downloading 11.4 Drivers to double check cause apparently there is issues with 11.5 its such a pity though i have noticed some graphic glitches fixed with these new drivers. eg i can zoom out of my plane external view the furthest possible and shadows wont disappear or my 2 fuel tanks 1 tends to disappear when i am at its furthest zoom but not anymore. I noticed some flashing graphic issues in a couple of other games have disappeared because of these new drivers but not affected my performance in them except SF2. I am lost and confused.........

Ok nvm ATI Drivers 11.4 fixed everything including my graphic glitches and improved my fps...

 

11.5 and 11.6 is a no go.

 

apologies for wasting ur time my fellow pilots..

I have a new ATI 6970 and when I tried the 11.6 drivers and my FPS dropped to 30, so i went back to 10.12 drivers that I used with my old ATI 4890's and my FPS went back up to 60.

yeah i been reading that there is some serious issues with 11.5 and 11.6 :boredom:alot of ppl with the 5xxx and 6xxx series are struggling with it.

11.2 on a 6950 here no problems whatsoever smooth 60fps.

EDIT **ack** below I'm on DX9 in SF-1, wrong forum sorry...

 

 

 

 

Odd: I have 4850 (I'm sticking to it) and I re-install Win-7, and before I install teh Cat, I get great game fps and smoothness. Then install Cat 11.3something, but no matter what I do with that, SF loses framerate *and* is more jerky -- fps jumps far more reaching into lower values.

 

So I go back to Cat 10.4, same thing. 10.3b, same thing. So I DELETE my ATI Cat drivers entirely, and I'm back fast and smooth.

 

I think the basic ATI drivers in Windows is doing fine, but for some reason, the Cat and stuff are messing me up. Dunno.

 

I'm going to go Cat-Free free for now.
