I'm not sure what's going on.  My system specs aren't the issue.  It must be software but I can't pinpoint it!
My drivers are up to date.
I'm running Win11
CPU I9-12900K
GPU RTX 3090
MB  ROG Z690-A
RAM 128GB DDR5

Hey choctaw111,

You'll need to post a log for the tech gurus to be able to help. The stock file is log.lst, enable it in the conf.ini and post it here. There's a post here somewhere with more details on posting the log, do a search.

Here's the relevant section from my conf.ini:

[HotKey Console]
Shift Tab=Activate
[Console]
HISTORY=1024
HISTORYCMD=1024
LOAD=console.cmd
SAVE=console.cmd
LOG=1
LOGTIME=1
LOGFILE=logfile.txt (NB: I changed this filename from the default.)
LOGKEEP=0

Make sure that you're running in Opengl and that you have HardwareShaders=1 set in the conf.ini

Good luck,
Cloyd

Thanks, man.  I'm going to have a LOT of questions as I work to get caught back up again

[choctaw111]

I did a little more research and changed some NVidia settings.  Now I'm getting 1,000FPS in the menu and about 275 in game.  I think it's time for higher refresh rate display

[Cloyd]

Cool, glad you got it sorted out. Those ridiculously high FPS numbers make more sense with your hardware.

Thanks, I'm getting there.  It still runs in windowed mode even though "Full Screen" is set to "1" in the conf.ini.  In game, the switch is set to "Windowed".  When I switch it to full screen, the sim crashes.  I've never encountered this before.  It's not bad if I'm running at native res of 3840x2160 even though it's windowed is still full screen

[Cloyd]

Here are my [window] section settings in my conf.ini (These are from my ancient laptop, but I think they are the same as my desktop.) Check to see if your settings are different. (Other than screen size, of course.)

[window]
width=1366
height=768
ColourBits=32
DepthBits=24
StencilBits=8
FullScreen=1
ChangeScreenRes=1
EnableResize=0
EnableClose=1
SaveAspect=0
Use3Renders=0
Use3RendersUI=0
WideScreenFoV=1
UIColor=0
UIDetail=0
UIBackground=rnd

[choctaw111]

My ChangeScreenRes was set to 0.  I didn't catch that.  Thanks for sharing your settings

Better Try 1920x1080 or even a Higher Resolution.

I'm late on this, but there's something else you can try if you're still interested in messing with the "fullscreen but still windowed" thing.

I was running the game and getting ridiculous framerates, but it was causing some irritating coil whine. So I tried to limit framerates and it didn't work. Most of that is irrelevant to what I discovered, though.

Windows does voodoo in the background to "help" full screen games benefit from its built-in scheduling and other bells and whistles that generally make it easier to Alt+Tab in and out of the application and make all the programs you're running play nicely together.

If you go into your game directory and right click on the il2fb.exe, select "properties", and then go to the "compatibility" tab (just next to "general"), in the second "box" down on that tab, there are several options.

Check the box that says "Disable fullscreen optimizations". Apply and Okay.

Now the game will run in true fullscreen mode. The effect for me was that the GPU now caps at 240hz, which is the refresh rate of my monitor, and Freesync can just do its thing. And I don't have to listen to the squealing while the GPU rips out 1,000 frames that I don't need.

If I understand the Windows tech correctly, the fullscreen optimizations essentially "trick" the program into thinking it's running in full screen so that it can behave that way in the running environment, but Windows is actually running a windowed full screen so that it can keep everything else running on your system more easily and smoothly accessible. Disabling the Windows fullscreen optimizations removes that extra step. I've found that the graphics settings recommended for the conf.ini are a lot less prone to doing weird, unintended things with the optimizations disabled and the game running in a true fullscreen mode.

Oooo, nice.

Turns out I was mostly understanding how full screen optimizations work, but was NOT understanding the extent to which windows still hands over almost all of the system resources when the game is "front and center", so to speak.
