Why GFX card with more RAM?

I have set almost everything on medium or low except some kept
at high and the FPS drops to 10 or 20 over cities.

So I'm eagerly awaiting the patch becasue a new GPU isn't on the
horizon for me

Thats a nice setup but still a midrange system.
The GPU's are what are holding you back a bit, especially if in crossfire because the game isnt working with crossfire unless you force it with some workarounds.
The CPU is still ok too unless your playing at lower resolutions, in that case it will hold you back too.

I have 2 6870 xfx black editions, with cliffs of dover i take it out of crossfire,an avg.60-70 fps on atag server. When i use crossfire pushing to get 20-30 with all settings high, orig. an med. so try with out crossfire salute

But the intresting thing is that the cpu stays at 40% load maximum in game and
the cards never go above 40% load. It could be that the memory on the cards
is filled and needs cycles to swap and clean itself but i have no stutters at all even
over cities. Just a fps drop from VSYNC 60 to 12-20.

Stutters and FPS drops occur when the 1st core is loaded above 75-80%. Overall CPU load may remain very low at the same time because usually there are 4 cores in total. Therefore it is necessary to monitor load per core and overclock. (2.8 to 3.8 helped me a lot).

My video card is loaded 98-100% all the time because it is a bottle-neck in my system.

AMD @3.4 can be a bottle neck because it is generally slower than Intel nowadays and especially in case it is Athlon it has very low or no cache at all which is extremely important for gaming. In case it is Phenom and not Athlon it has some cache but a lower one than modern Intel processors. Gaming benchmarks on PC sites usually show this very well.

Vsynk causes fps to reduce in big steps from 60 to 30 and then to 15. It does not allow you to have 29 fps even if your card is capable to render 29 fps. Try running with vsync off. If you need vsynk make sure you force triple buffering on with a 3rd party utility like ATI Tray tools or Direct3D Overrider (D3DOverrider) which is a part of RivaTuner.

GPU may be not 100% loaded if it is held back by vsynk too.

I installed a 2Gb version of the 560Ti and monitored vram usage. Just as a comparison I loaded IL1946 maxed to the hilt on a mission using Cannons Channel map - VRam was around 1.6GB so I knew that the extra VRAM was actually being called on at 1080p native res.

Using the Quick mission 'Bomber Intercept London' with 15 ac and Flak, etc.
I tested Vram using my CloD MP settings which are High except for Buildings/ Land Detail at medium and Trees Off, the max Vram used was around 1GB and FPS very playable even on a 2.7Ghz Duel Core - some stutters as you might expect over London.

Setting Textures to Original and repeating the mission added a bit more Vram use at 1.2GB. I then cranked every setting to the highest available except for SSAO and VRAM went to 1.6GB - at low alt over London the FPS took a severe hit but no suprises there on my system.

I don't particularly see a lot of Visual impact when having some settings such as Buildings and Land detail set to medium other than improved FPS and lower Vram usage. Dropping the resolution to 1600 x 900 and max Vram used was less than 1Gb using my MP video settings as described earlier.

My next upgrade will be the PC Mobo but will wait untill the next patch is out.

Thats interesting EvangelusE, the sim must scale to the available vram. I thought it might use as much as possible, is it possible that the sim doesnt realy show all the settings in game play that are chosen.

P.S. stop shooting at Ju88s

[SEE]

Don't know about the scaling as such. AFAIK, if you exceed the capacity of the VRAM by a combination of high video settings and Screen Res then I suspect CloD gets the data from elswhere, maybe Page RAM or the HD which I suppose would cause stutters, etc. Some one else is probably better at answering that question.

What I do know is that with everything at max and within the limits of the available VRAM fps drops significantly on my system probably because of the CPU speed and everything processed by one or possibly two cores.

Finally, I promise I won't interrupt your JU88 sorties again!

I was totaly kidding, you know I like shooting back at you lol

Triple buffering is in the default Nvidia panel above Vsync no need to add any other programs.
