BAT on a new PC
« on: October 30, 2024, 08:02:33 AM »

Hello,
I've recently tried to get back to BAT and 1946 in general after almost 8-9 month break.
I have run into serious problems running BAT on my new piece of hardware. I get frequent lags/stutters and quite often sound seems to freeze or loop indefinitely.
Has anyone run into something similar? I wonder if Win 11 compatibility may be the issue (from my experience it seems to have problems with many legacy games in general)

Any help, suggestion or even a trace to find a solution is welcome ;)

Best regards. o7

What type of graphics card?

This seems most likely a conf.ini issue of some sort. Did you use an old conf.ini? That's more a general Il-2 issue...
Make sure you have all the latest drivers and then build a new conf.ini. Maybe you can start with one of the the suggested ones in the BAT 4.0 post.

I've also run into memory limitations with all the high-texture mods and effects I've added over the years, which either prevents missions from running at all or slows them down considerably. 
However, Mike has announced that a new SAS Selector is in the works that should resolve this:

"Memory wise I'd suggest to wait for the next Selector/BAT/Ultrapack release.
That one works with 10.000+ aircraft slots, flawlessly.
Memory issues? Past tense please.

IOW: 32 Bit w/o LAA works pretty well for this ancient game."

... yeah... well, for SFS packed material, I'd say.

All stuff that accumulates "in the open" and out of sfs compression (and is not a java class), it will slow the game down. That is why big packs must come fully integrated and packed in sfs. You can not run a thing the size of BAT in unpacked state. Not even remotely.
Mike's selector can manage RAM better but it can't change the fact that IL-2 is 32 bit only for instance. It will push the java wall limit into the unknown, but that's not the issue if you have trouble displaying HD content. That's another issue altogether.

Its RTX4060. Laptop version.
I've checked the drivers already.

Conf.ini may be a good point though - I moved a lot of files, including the configuration and user profiles from the old install. Clean '46 worked fine though, once I started adding BAT things went south.

I'll try that and post any results I get.
Thanks

Update:
Conf.ini reset didn't help, yet I think I have found the issue.
Cause seems to be trivial - for whatever reason, Il-2.exe switched to running on integrated graphics. Going back to dedicated GPU solved the problem.
Beauty of integrated+dedicated setups  ;D

How did you switch to GPU? It seems that on my GTX 1650 Il-2 can work better, but during the game the video card does not work, instead the processor works at 50-100%. I have been trying to fix this for several years, I don't know if it is possible at all.

IL-2 is an old 32bit engine. It will always run on one single core of your main processor. That is where the load is coming from and you can't "shift it". It does not work like this.

With IL-2, the power of one single core of your main processor is always the bottleneck and kind of defines the general performance.  Any GPU you have running is only doing post-processing for display rendering in perfect mode.

Does IL2 have problems with Window 11?

Not at all, I'm using the same installation from an external drive that I had in Windows 7.
