Hmmm....it is very strange.

I had two days of great SLI playing on the REPKA Server #3 with 70-100 fps and no stutters.

The third day (today) I had a different experience:
Flying towards the enemy (blue) base island, towards a dogfight with many planes, my fps dropped to 6-14fps !!!!!

This time there were some planes more in the server but I still can not explain the difference.

So I am sad to say that the problems remain to be solved.
I can not however explain the first two good days of flaing though.

It is nice to see that some "inexpensive" NV cards appear in the market with >2Gb VRAM.

GTX570 2.5Gb VRAM

GTX560ti 2Gb VRAM

GTX550ti 3Gb VRAM

GTS450 3Gb VRAM

GT430 2Gb VRAM

Has anybody tried them with CoD?
I have my eyes set on these GTX570 2.5Gb but I wonder how much improvement I will get for 600EUR (I need two) just for increasing VRAM from 1,3Gb to 2,Gb ...

Update 28 October 2011

I stopped using SLI and fly only on a single GTX570 1,3Gb card after I realised that in sli mode I was getting less smooth game albeit I had almost double fps!

Thanks to the ATAG server (because it provided us with a very high end platform in terms of CPU (6xXeon), RAM (48Gb) and Bandwidth (10Mbps)- a great thanks to the members of ATAG!!!) I had the opportunity to test excessively my rig online at different settings.

Flying the English channel map with dozens of enemy planes and bombers, I have nice 50fps on a single GPU (and 90fps on sli but the game is not smooth enough fr my taste) at resolution 3024x1024.

I will post some pictures and my settings soon...

I still have problems, notably the current patch has a dreaded "memory leak" so watch your av ailable RAM indicator while flying, is it over 94% used, you are bound to exerience a CTD very soon. The only solution is to stop COD and restart the game. But it is less tragic that it sounds if you know and control the situation.


As a sum up, I will have to revise the title of my post, "sli is not really working" or to be more objective, the latest official patch (Oct. 2011) made the game easily playable with med range 1,3Gb VRAM graphics card (as long as a 570GTX is considered med-range).


This is a big improvement and congratulations to 1C! (of course, there is we expect).
