Hello, I'm having issues with tessellation.
When i ran unigine heaven 2.1 benchmark i didint have any tessellation at all, then i read up that i should uninstall all of my video drivers and reinstall the newest ones, so i did using Driver Sweeper in safe mode, then when i installed the 10.9 ati catalyst driver suite i ran the unigine heaven 2.1 and i had tessellation it looked cool and all, then i rebooted my pc and tried again, and there wasnt any tessellation again. help please ?

But thats a huge downgrade, i mean there were many performance updates since 10.3 ?

Do you have some facts to back that up?

well, i tested that my self...uninstalled 10.9 and installed 10.4 (which i think the most stable version of CCC)
and everything is much better...even got a 1 or 2 more fps in some games :)

Well, i have to disagree with you mate, i ran heaven benchmark with both 10.9 and 10.4, and 10,9 show better performance, here's a screenshot :

tried 10.3 , so its definitely not a driver version fault. what could it be ? any ideas anyone ? maybe it has something to do with the bios of the card? (ain't a fan of flashing vga bios)

I think its a windows problem, i dont have the support for dx11, cant run any game with dx11, says unable to initialize dx11 or games just crash on load.

You are arguing points that are mute, do to different system setups you will find that different ATI drivers perform differently. I have a 5850 and found 10.4 to run best, ATI has since made improvements in some parts of its drivers but I found that in the games I play 10.4 had the least issues and ran the fastest.

I tried updating directx, I'm thinking of reinstalling windows, but dont think that it will give any results :/

You may get best results by doing so.

Hehe, after a few reboots it looks to work fine, thank you all for trying to help.

Seems that reinstalling windows solves everything after all :)  p.s if anyone's interested im running 10.9 now
