Well, I rebooted in Vista which does not happen often... Uninstalled the beta SP1 and installed the real one. Installed the Nvidia Forceware 175 64-bit driver and booted IL2 to laugh at Vista again... Right from the beginning something felt wrong. It did not feel like I was on another computer like it used to do when booting into Vista... Started fraps usning the EXACT same settings as in XP (copy of the same directory). These where my results now:

Vista 64 Ultimate SP1 (4.09 OpenGL all maxed out in settings and conf.ini (72km etc) - 16XAniso+16QX AntiAliasing etc.)

2008-05-13 23:48:36 - il2fb
Frames: 10444 - Time: 155165ms - Avg: 67.309 - Min: 20 - Max: 114

I was shocked and booted back into XP 32 and rerun the exact same settings:

XP 32bit SP3 (4.09 OpenGL all maxed out in settings and conf.ini (72km etc) - 16XAniso+16QX AntiAliasing etc.)

2008-05-14 00:00:59 - il2fb
Frames: 10638 - Time: 155549ms - Avg: 68.390 - Min: 23 - Max: 118

Adding my score from february 2007 posted above for easy comparison:

XP(SP2):

2007-02-05 22:52:04 - il2fb
Frames: 9886 - Time: 155544ms - Avg: 63.558 - Min: 31 - Max: 113

Vista 32 Ultimate:

2007-02-05 23:00:09 - il2fb
Frames: 6571 - Time: 155252ms - Avg: 42.325 - Min: 19 - Max: 87


What the heck! Vista is supposed to be crappy at OpenGL. It must be SP1 that did the trick, or is it some magic with the 175 Nvidia driver? Following the same tests as in february 2007 posted above I also started a straight A20 run in Crimea with no AAA.

XP - 106 fps
Vista 103 fps

XP has dropped from 115-120 at maxed settings compared to the 2007 results but this is with 4.09 72km so it looks a lot better... The amazing conclusion is that Vista is now just a few percent worse than XP. I never thought I would say it but Vista seems to work for OpenGL games now! The problem is that the damage is already done. I guess that Oleg was shocked about how bad OpenGL worked when Vista was released and redid the whole engine in DX10/9 causing a 1 year+ delay as he realized OpenGL was going to die with the poor Vista preformance...

Well - back to this thread - Skarphol, have you installed SP1 for Vista? Are you rinning the 175 forceware drivers for your Nvidia card?

Good luck! /Maxex

Processor affinity
 

New e8400 here with 8800 gt oc, 2 g ram, xp sp3...

With duo cores
process affinity = 0 = core1
process affinity = 1 = core 2
process affiniity = 2 = both cores

I never tried running it using a specific planes "viewpoint". I always ran the BD from the "default" viewpoint that switches from plane to plane. That is where you get the real hit in fps as the view switches to where all the action is.

The game suffers from FPS drops overallt it's nothing unusally i've same system as you except i've one of the newer gts the 512mb version. There's some areas and citys that just completly drops fps when flying around / threw.. and that's not because the graphic card can't keep up but more of a leak in the Ingame engine. Remember it wasnt built for thoose graphic cards in mind.

Thanks for all of your replies!

Yes, I am running the Service Pack 1.
The current drivers of my graphics card is "7.15.11.6906" according to the device manager. I have to check out what "Forceware 175" is.

I will have to do some research into this, but really don't have the time nowadays.

Skarphol

Then you have the Forceware 169.06 which is rather old (but what the performance gain is going to 175 is naturally hard to tell, they claim OpenGL performance improvements in the 175 readme). The current version is 175.16 - download it here (64 bit Vista version):

OK.

I upgraded the driver and now it says "7.15.11.7516" so I guess the driver has been updated as it should.

With DirextX I got an average of 90, the same as before I upgraded the driver.
With OpenGL I got an average of 51, a ca. 50% increase in framerate..
but the graphics went very bad!!
Look:

I'll check on this tomorrow.

Skarphol

Well, sorry to hear about those problems. Are you using the latest graphics dll:s released for IL2?

Check this thread:

http://forum.1cpublishing.eu/showpos...5&postcount=41

/Mazex

EDIT - download both zip:s and unpack them. Do backups of the files "il2_core.dll", "il2_corep4.dll" "il2setup.ini" and "conf.ini" in you IL2 dir before coying these files there. Then run IL2Setup.exe and select "Nvidia Geforce 6xxx...9xxxx"... in the video settings tab (and OpenGL 32 bit on the first). Goto conf.ini and change the following lines to your preferred resolution (1280x1024 in my case as that is my 19 inch monitors prefered resolution):

[window]
width=1280
height=1024

Ah! you got something turned on the game doesn't like try messing with the il2setup and choose the correct card for the GPU.
