FPS Problems - Possible Reason?

[Halsfield 1]

Obviously a lot of people are reporting FPS problems with the latest set of patches. I think I might have found one of the culprits. I found this line in the changelog that must have been added somewhat recently:

"[94912] Fixed: Video memory detection on W7/x64 sometimes wrong because of bug in IDirect3DDevice9::GetAvailableTextureMem."

Now, when I go into the game and mess with the video memory settings (from low/medium/high/very high/default I think) it does nothing. Default should be the best option and provide the most performance b/c it will use the proper amount of video memory (1gb for my video card) instead of the 512mb that "very high" is capped at.

I also use windows 7 x64 so this fits perfectly into why I'm having problems. Of course the changelog says it is fixed but maybe it was added to the changelog and not the live version?

Backstory: Have been playing on very high settings across the board for many weeks now and not had a single thought about FPS problems. Then steam updated Arma II and my fps went into the toilet. I can get it to a meager 20-30fps if I crank everything way down and use some other shenanigans like command line parameters and changing .cfg files.

That's been in the log for the past 5 beta patches. The numbers at the start of the line tell what beta patch they were introduced in.

Well, I'm all ears for other reasons. There have been ~5 beta patches in quick succession over the past few weeks. Maybe one of the recent patches undid one of the previous ones. It just lines up perfectly with what is going on. I have windows 7 x64, many others don't which would be why not everyone is having trouble. My in-game options for video mem is not working whatsoever and that would account for why my fps dipped heavily if its only reading 1/2 of my 1g @ 512mb.
