Ok, I have some test results.

I replaced the 'mg_snd_sse.dll' file from 4.09 with the one from 4.08. I then ran a long (over 2 1\2 hours) test session. Normally, I would have had some freezes and eventually a total lockup by then. However, I had no problems at all.

I'll continue to use the dll from 4.08 and see if IL-2 continues to run normally.

Make sure you desk top res and game res are the same when running the high end settings with the new dlls.

I had my desktop set to 1920x1200 24" LCD and my 2nd screen at 1600x1200 refresh rate at 80 " it a 21" CRT " When I didn't have both screens set to 1600x1200 at 60 refresh rate " max for the LCD " it would lock up and crash if I had to Alt Tab out.

This could also be a problem for other testing the 4.09.

After setting both to the 1600x1200 " same as i use in game " the problem went away.

As for the sound I'm using Vista 64 and and X-Fi Gamer with the latest drivers and they are working great. I love the new sounds.

I cannot confirm this. I run my desktop @1280x1024 and IL2 @1600x1200 and I switch between desktop and IL2 pretty often to answer ICQ. I got an nVidia 8800GTS, though.

It could be a non issue if you desk top is LOWER setting than the game were mine was at a higher setting.

Asus 7900GS with NGO 1.16.218 drivers and Core2 6300 CPU. Running at 1280x1024 with 4xAA and 16XAF

Had some weird issues with 4.09 dll’s.

-In one session above Pearl Harbor my FPS would plummet to very low when I was looking straight down above water (=3) in my cockpit or from the outside view . Ended the mission, closed the game, restarted the game and the mission again and the problem was gone.

-Have flickering of the dark openings of the hangars above Pearl.

-Cannot use 8xS AA because of strange spike like reflections in the water (=3)on the horizon.

Hey,

I got a very similar system with even the same drivers. Using Thor's gfx dlls and 408's sound dlls though.

I couldn'T believe you get constantly 60fps with these settings so I set them to my conf.ini and nhancer just as you do. I tried the Slovakia map and no.. over cities I'm going down to 17..25 at times, especially from the pit or zooming out in the external view. Changing to 8xS SuperSampling AA I got low 20s as minimum flying the same route. As long as I stay away from the cities or don't look at a whole city it's +/-60..

Maybe I can upload a track of my flight so you can tell me yours? Not that I am wasting performance somewhere...

Found somethign odd though. changing to MultiSampling AA didn't bring much more fps, especially 4x and 8xQ actually left a slower impression and even went down to 12fps at times.

My System:

e6850 @ 2x3.0GHz (dual or quad core should make any differences in IL2 anyways)
4GB DDR2 800MHz RAM at LowLatency
ASUS PK5-E
MSI 8800GTX OC
169.25 whql
vista 32 up to date

Sooo .... is there any update or work around on this AMD issue ?

I do have 4.09b1m running fine using the old version of mg_snd_sse.dll (Sempron2400+, and as with everyone else running old Athlons - 4.09b falls over with the new dll) however it would be nice to try the new sound dll.

6 months ago i posted on All Aircraft Arcade a comment regarding the fps problem with Slovakia map(i have your problem).In that thread they was talking about the numbers of object in a Battle Of Britain Mod Map and after a while i was following the discussion i posted these comments(see my nick Deovis):

pay attention to the reply of one of the Slovakia Map designer!!!

The new DLLs did get rid of some of the weird shadows shifting when running in SLI.

Too bad it doesn't fix the SLI "hearbeat" stutter that plagues this game.

Running 2 8800GTs 512s in SLI with 177.66s and its been a problem the last 20 revs of the drivers.

Hm, possible.
