Tried that
 

Thanks Flanker,

Interestingly I did try the Lost Planet profile as discussed in this forum. I do take notice of what you guys recommend;)

However, the sky was just flickering constantly. So, I experimented and tried other profiles after downloading the latest CAP from AMD and randomly found that the Warhammer Space Marine profile worked perfectly. I was on max settings and getting 35+ FPS all the time with no stutters, flickers or anything.

The only problem I could find was that the lettering in Mission Builder was all "fuzzy" but still readable. Once the game was started it was fine. On leaving the game I disabled Crossfire in ATI Catalyst and went into my Windows Live Mail - the lettering in the menu sections was "fuzzy" but the email notes themselves were crystal clear? Will have to play around with display settings to sort that out.

For your interest I have attached the ATI Catalyst settings that I applied to the profile.

This is due to the Morphological filtering setting - it tries to AA everything (one of its draw-backs). I use SMAA instead (search for one of Buchon's posts, he has a link in his sig), which gives (relatively) good results with no performance hit. I'm not sure if you can change an individual setting in a selected X-fire profile while it's active, but if you can de-select this option you'll find that the fuzziness disappears.

Thanks
 

Good to know there's someone still looking over my shoulder:)

Green smoke and ground dust?
 

My new rig is performing very well. I have tried various settings and AMD CAP profiles. As expected, the Lost Planet 2 profile seems best graphically but the screen does stutter quite a lot when Crossfire is enabled. If I try other profiles (i.e. Space Marine, World of Warcraft) the stuttering is less but sometimes I get green smoke, green gun smoke and ground dust? Is that to do with the various profiles and how they treat colour individually? When I clear the cache it sometimes reverts to normal but not consistently? Any ideas what may be happening?

The good news is that I can now fly on max settings achieving FPS rates of 60 + most of the time. I am using Speedfan to show GPU and CPU temperatures on a separate monitor linked by HDMI and max GPU has been 65 degrees and max CPU 55 degrees - is that acceptable?

The Gigabyte Easytune 6 software wouldn't install successfully - do I need to look into the BIOS at all? I don't know enough about BIOS settings and I am fearful of changing anything without real knowledge.

I have installed the latest 1.07 patch and SMAA.

Green Smoke sussed - I think?
 

Since I installed the 1.07 Beta patch it seems that any missions I created before the install are "corrupted" slightly and the green smoke/dust appears. When I start a normal Single player game everything is normal. I will create a new mission and see if that is indeed the problem to prove the issue.

Any others experienced this?

S!

Sometimes I have seen this greenish smoke, but random phenomenom only. If I had a second 7970HD I could experiment a bit more, but more than happy on the performance of one already :) GHz Edition is on it's way unless something interesting pops up :)

Plan to reinstall COD
 

One thing I haven't done is reinstall COD from scratch - I have the CD that the missus bought me (and has regretted it ever since 'cos I spend so much time either playing or tweaking!!)

This paragraph from one of the posts intrigues me:- "*Reinstalling The Game after the latest patch has proven to be a performance booster."

I have recently installed the latest 1.07 patch. If I reinstall the game as suggested, do I uninstall first - in which case what happens to the patch tweaks? - or just reinstall over what I have and everything will fall into place? I gather a new Beta patch is due imminently.

Will I lose missions that I have created? I am still getting green smoke and dust in Mission Builder files whether old ones or newly created. Is there a fix for this. Nothing I do with CCC settings makes any difference. The standard Single player games are fine?

I also have Buchon's SMAA installed. I assume I just reinstall the files after the program is installed?

Would appreciate some guidance (again!).

Thanks
