Helrza, I believe I have already copied and pasted your conf.ini settings (changing the process aff mask, of course)--I think I've tried every tweak currently proposed by anyone. The game is just barely playable with low terrain settings when launching from airfields near the coast, but stutters are still an immersion-killer, so I prefer to just play as far away from land as I can get at the moment, hoping that patches will make the campaign a more pleasant and less painful experience.

Oldschool, my native resolution is 1440 x 900, so that's the res at which I've been playing the game. Wide-screen, there is only one lower res really available to me, which I briefly tried. I don't think it made any detectable difference to performance, and the degradation of visual clarity was pretty bad. Maybe I should try that again.

I've disabled Aero, tried multiple page-file changes, used a flash drive to "Ready Boost" my OS, defragged the game and the HD, OC'ed my GPU (can't OC my CPU in any way with this MOBO), installed the performance mods, disabled all unnecessary services, created exceptions for the game folders and the .exe in my anti-virus, tweaked the NVCP no end, although I don't think NVCP has any effect on the game at present, tried all possible Options graphics combinations, tried setting process affinity and game priority in task manager, and installed the latest Beta drivers from NVIDIA.

I've been somewhat haphazard while attempting all of this, and I am sure there is a specific combination of all the above that would be ideal for my particular set-up, but like IL-2 1946, apparently, it is going to take a lot of research and experimentation to hit upon it. And the knowledge base for the research only exists as yet in a primordial form.

Good news about the patch, Bewolf--at least they are coming out quickly. Hopeful about giving it a try.

I don't think the process affinity mask is working for me. I have it set to 2, which should cause COD to run on my 1 core, leaving 0 for the OS. But tabbing out of the game, Task Manager shows Launcher.exe to be running on both cores. Setting affinity in task manager to use only core 1 causes the game to load missions very slowly, and I do not see any improvement over land. I see no difference setting a higher priority in TM either and that seems to cause audio sputters.

Does anything in NVCP work at all? What about Anistropic? Something I read about the game not being in true Full-Screen mode, and about that breaking driver imposed AA has me befuddled about all of that. Anyone know?

Just remember that anything you turn on to clean up the eye candy (AA or AF) will have an impact on your fps. 4X AA can lower your fps by 30-50%. As well as increasing your resolution. Im starting to think that most people here dont realize what effects fps. EVERYTHING effects fps especially resolution, AA, AF etc etc. AA and resolution have the biggest impact.

I have avg fps of 65-85 depends how many planes and what is near bit still game is not smooth at all, specially above the land...so its more about optimisation of the sim than our hardware

If the video memory gets overloaded that will cause stutters for sure. You are unlikely to see the stuttering go away until the game textures are reduced in size or compressed so that the video memory in use is below 1Gb for the high end players and 500Mb for the mass market. Turning off all AA and AF will certainly help keep video memory use down but the main problem is almost certainly high resolution textures.

It would be interesting to see some results from Rivatuner of video memory in use at various settings.
