can you check your vram usage?

it looks like you are going over the 1gb frame buffer of the gpu.

For me it seems the betapatch was better than this one. I seem to have more stuttering over land than with the beta patch. Over water teh performacnce is good. Over land its good too but the stutters kill it.

SYSTEM:

Core i7 930 @4 GHz
GFX: GTX 480 SLI (onl one activated)
RAM: GSKILL 6 GB Tripple channel
MB: Gigabte X58 A- UD5

I'd expect the GPU to max out and it certainly did with the vanilla version and beta patch. The CPU on the other hand I'm confused about. This morning it was maxing out the first core and I could play reasonably smoothly with some stutter, mainly over built up areas. Now the same CPU core isn't being utilised fully and the stutter is terrible.

I'm assuming this is the reason for the performance drop. Anyway I don't want to make any more noise about it, let's get some more feedback from others.

i have those black glitches (on the first picture) too. But the game runs fine on high.

First post to say how impressed I am with this game now

With this new patch I'm getting great performance with graphics set to high. This is easily the best looking game I've ever seen and the fps I'm getting for how good it looks is really impressive. The ability to look and move about the cockpit with the mouse is really immerse compared to il2 1946. I found myself taking a hurricane up to high altitude with the engine starting to labour and cut with the advanced engine modelling. After spending a while setting keys and operating pitch and mix with ctrl + throttle and shift + throttle, I was looking at the exhaust colour and trying to get the best mix - so immerse.

I burnt damaged the exhaust a bit after messing up coming back down ;) Landed slightly hairily and watched the trees and grass blowing in the wind.

A combat engagement near the cost with about 10 planes ran the same - really well.
Over London I get slightly lower frames at low altitude - but still felt like a fightable fps. I'm not getting the big variation and jumps at all.

I'm getting at least 30-40 fps and often more. Stuttering is mild

Just awesome - I'd recommend right now to anyone with a powerful single card setup. It's probably gotta be a GTX280 or 470 or better - but man it's worth it! Can't wait for SLI and further fixes. To anyone that doesn't know, these guys will give us years of updates and new planes - just wait and see.

nope, 280 isn't good enough, speaking form personal experience.

got to be 4 series or better.

Interesting - that (edit) may be an indicator that DX11 shader performance is important. I know that things like tesselation etc are much more optimised on the fermi cards. I believe that in most DX9 games a GTX470 and GTX280 are equivalent

in fact it's gotta be 470gtx 1.2Gb minimum to be more precise

I think the use of "got to" should be avoided - but you may be right. To clarify - I just mean that we are guessing at where the bottlenecks in systems may be

I am starting to find this all getting a little irritating. Nothing seems consistant at the moment. I am not even sure if the patch has downloaded and installed. I can see no version number on any of my screens. Something downloaded and my axis controls were suddenly changed around so I can only assume it has.
The frame rate dropped drastically and the more I reduced the video settings the worse it got until eventually flying the quick mission over Dover with just the Hurrican and everything set on minimum I was down to 10fps. So I just wacked everything up to maximum and the fps immediately jumped to 40! Until I got close to the ground when the fps evaporated again.
The things that gave me better fps on the deck were turning off grass, setting buidings amount to high and buildings detail to very low. Even with forest on very high I am getting 30fps down low but the biggest factor was turning AA down to 2x. And the landscape looks pretty good.
When I checked the performance I found the CPU Usage was only about 14% until I changed the affinity mask to 15 when the usage doubled to 30%.
I still don't think things are as good when multiple aircraft are around with even more stuttering than pre patch. I think it's just a case of experiementing and waiting for more patches.
One thing that did make me smile is that if you look at the heads of some of the bolts, the ones on the seat back of the Hurrican are good, you will see they have a word I can't quite make out and Maddox Games embossed on them.
