*****8800GTS (512) vs GTX 285 (1024)*****

These first few benchmarks are using the same settings as those used above, but with an eVGA GTX 285 running 185.68 drivers in place of the 8800GTS 512:

Windows XP
4.08, E8400 running at 3.6 GHz, GTX 285SC at 675 MHz core, 1548 shader clocks, 2538 memory
1680x1050: 8xAF 2xAA max quality Start at 0:03 end at 2:32
Avg: 121.681 - Min: 29 - Max: 285 ::: Here I see a gain of 28.55 fps compared to the same run with the 8800GTS 512.

Windows XP
4.08, E8400 running at 3.6 GHz, GTX 285SC at 702 MHz core, 1584 shader clocks, 2646 memory (SSC speeds)
1680x1050: 8xAF 2xAA max quality Start at 0:03 end at 2:32
Avg: 122.847 - Min: 29 - Max: 284

Now going up to 1920x1200 resolution I will evaluate GPU scaling at 3.6GHz:

Windows XP
4.08, E8400 running at 3.6 GHz, GTX 285SC at 675 MHz core, 1548 shader clocks, 2538 memory
1920x1200 8xAF 2xAA max quality Start at 0:03 end at 2:32
Avg: 111.328 - Min: 29 - Max: 285

Windows XP
4.08, E8400 running at 3.6 GHz, GTX 285SC at 702 MHz core, 1584 shader clocks, 2646 memory (SSC speeds)
1920x1200 8xAF 2xAA max quality Start at 0:03 end at 2:32
Avg: 113.148 - Min: 29 - Max: 284 ::: Overclocking the GPU from SC to SSC speeds we gain 1.82fps average.

Now to see how things change with higher AA and AF settings at 1920x1200:

Windows XP
4.08, E8400 running at 3.6 GHz, GTX 285SC at 675 MHz core, 1548 shader clocks, 2538 memory
1920x1200 8xAF 8xAA max quality Start at 0:03 end at 2:32
Avg: 105.305 - Min: 28 - Max: 263 ::: So going from 2x AA-> 8x AA we lose 6.02 fps average.

Windows XP
4.08, E8400 running at 3.6 GHz, GTX 285SC at 675 MHz core, 1548 shader clocks, 2538 memory
1920x1200 16xAF 16xAA max quality Start at 0:03 end at 2:32
Avg: 98.539 - Min: 29 - Max: 256 ::: Going from 8XAA & 8xAF -> 16xAA & 16xAF  we lose 6.766 fps average.

Windows XP
4.08, E8400 running at 3.6 GHz, GTX 285SC at 675 MHz core, 1548 shader clocks, 2538 memory
1920x1200 16xAF 16xAA and Water=4 max quality Start at 0:03 end at 2:32
Avg: 83.216 - Min: 26 - Max: 222 ::: Going from Water=1 to Water=4 we lose 15.323 fps average.

Cool, thanks!

Not really enough difference to speak of.  The good news is that windows 7 does not take any noticeable performance hit so that Black Shark will run at almost 2X what can be achieved in XP.

I won't be surprised if Age of Flight and Storm of War behave similarly to Black Shark.

Thanks again for all the testing!

P.S. - It's really great posting on this new TX-forum software  ;D

Yeah, I didn't really know what to expect, but I had a feeling that given how IL-2 performed in Vista vs XP, that there might be a slight decrease in performance here.

Of course the difference between 90.7 and 93.13 fps is absolutely imperceptible at this resolution. SimHQ did an OS shootout between XP and Vista and saw the following: http://www.simhq.com/_technology2/technology_110c.html

On a machine that struggles to run IL-2, perhaps the difference could matter. . .but probably not by much.

Frames, Time (ms), Min, Max, Avg
 10240,    150985,  18, 157, 67.821

Initial Il2 clocking on new system.....
Il2-res 1600 X 1200
Windows Vista 64
E8500 @ stock clock
GTX-280 @ stock clock w/ 181.22 drivers

Copied Open GL section from Eco's post into my [Render_OpenGL] section in config.ini

Duplicated Eco's Nvidea settings below:

Anisotropic filtering = 8x
Antialiasing - Gamma correction = On
Antialiasing - Mode = Enhance the application setting (?)
Antialiasing - Setting = 2x
Antialiasing - Transparency = Multisampling
Conformant texture clamp = Use OpenGL specification
Error rept and Extension limit both off
Force mipmaps  = None
Maximum pre-rendered frames = 8
Multi-display/mixed-GPU acceleration = Single display performance mode
Texture filtering = Off
Texture filtering - Negative LOD bias = Clamp
Texture filtering - Quality = High quality
Texture filtering - Trilinear optimization = Off
Threaded optimization = Off
Triple buffering = On
Texture filtering - Aniso mip filter optim = Off
Vertical sync = Force off

=================

Look ok?  This is blazing speed for me...

Set Antialiasing Mode to override the application setting, at enhance AA will be off in IL-2. Also, how did you come to use the value of 8 for maximum pre-rendered frames? On your machine I think you would be better off closer to the default of 3. You can verify this by looking at frame rate volatility.

You need to seriously revise this settings and it will be fun  .. ;)  look also in IOCL into Eco's set or the one on il2 corner

Did you, by any chance, do a comparison of Vista and Win7?

I don't have Vista, and since I've got 7, I don't imagine I'll get that chance - it's hard to justify buying a copy just for BlackShark, and right before 7 comes out!

That said, word on the street seems to be that 7 is just a little faster than Vista overall. . .it would indeed be fun to see how much faster it is though!

OP updated with 8800GTS vs GTX 285SC results.

Thanks for the update Eco.  It all helps.

From my experience thus far they have fixed the crippled TCPIP stack in Vista, without my intervention of course ! :).  Overall 7 is peppy with a few minor configuration changes to calm down the gui-riffic cartoon interface in the new aero.. Windows wanting to be linux.. or mac, its incredible, but it works.
