Here some tweaks to improve framerate.

[FS~Phat]

I got a big improvement in every situation over water, land and down low strafing London. Still the occasional hitch as textures are swapped in GPU Vram but 40-45FPS strafing London in cockpit view is a huge improvement. I have 64FPS external view at building level in London. Over water Im at 100FPS consistently.

I now also have all graphics options set to max including unlimited buildings with roads and grass on & shadows off with no AA. No SSAO and No Mipmaps @ 1920x1080.

Experimenting with different settings with the game paused in London at building level with an external view, shadows is the heaviest overall impact on FPS performance, Roads and Grass are next followed by number of buildings. AA is a big FPS hit for cockpit view but not so much external, seems the AA is pretty much limited to the cockpit details.

All the other settings only vary avg FPS by 2-3FPS each compared to 10FPS+ improvement by turning off various check box options. The trees and building details seem to effect the smoothness of play but not the overall FPS too much at least on my system.

With SSAO off and some coding optimisation for texture swaps, Mipmapping and texture sizes from 1C I think the issues can now be quickly resolved for the majority of users!

System Spec
i7 950 @ 4.6Ghz
6GB DDR3 @ 2000Mhz
4 x 5870 GPU @ 1000/1300 (2 x 5870 + 5970)
2 x 128GB Vertex2 SSD RAID 0

Huge improvement on a Q6600, 2gb DDR2, GTX260 low end job. Using a lower res than desktop but getting playable 35-45 over land with shadows on, low trees and medium shading. Previously I was getting 7fps. still stutters a fair bit down low, but the 8gb ddr3 that I've got on the way aught to look after that.

One thing though, I notice land textures are very blurry at altitude. Would disabling some part of the mod fix that?

Good BE Hardware article that both describes and shows the effect of SSAO on various scenes and video cards.

I wonder why 1C thought this was a useful effect for a flight sim? Looks to me like its most suited to first person shooters.

you aren't alone, it look like to me too....
very useful in COD

The only area its really noticable in CoD is in regards to the grass, it helps makes them look like they are casting a shadow. Without SSAO the grass just looks like it pops out of the terrain. However its not worth the performance hit at all.

I know nothing about SSAO, but wikipedia indicates that the method has the following advantages:

• Independent from scene complexity.
• No data pre-processing needed, no loading time and no memory allocations in system memory.
• Works with dynamic scenes.
• Works in the same consistent way for every pixel on the screen.
• No CPU usage – it can be executed completely on the GPU.
• May be easily integrated into any modern graphics pipeline

If framerates increase when SSAO is turned off, doesn't this indicate serious issues between the game code & most GPU's?

Hmm SSAO is an item listed in the NVIDIA control panel. however when I try to create a profile for it it says "not supported for this application" and in Global settings its OFF anyway.

Though pointing to COD launcher.exe results in the FC2 Launcher.exe icon appearing so whether its really looking at COD or FC2 who knows.

So maybe ? it can be done through the Nvida CP ?

SSAO gives me problems with "Amnesia: The Dark Descent" (fps fall). It needs to be optional.

This mod points in the right direction. I was actually playing this game for the first time a whole evening long and really enjoyed it. Its actually very immersive, when everything will run as supposed. Combat feels much more real than in 1946, at least for me...

About SSAO: TOW: Korea as an example was only playable after I shut it off. This one is very heavy on GPUs in general, and not worth the gain in IQ. I preferre good made mid-res textures....And for a flight-combat-sim its useless most of the time anyway.

The biggest hog for me now: Buildings seems to show allways full detail, even on the lowest setting. Sure its incredible attention to detail, and looks very good. But fluid skimming is not possible at the moment. Less is more...

LODS handling in general should be more aggressie IMHO. Not to the extend of 1946, but a bit more would not hurt....

Thanks a lot to all involved in polishing up this gem

Hi,

just tried the NOSSAO mod and performance increased a lot on my rig.
Now i just have to get rid of stuttering and it is almost perfect
