I hope everythings works perfect than also on AMD 7000 cards.

IL-2 issue on AMD GPU's is fixed with the next driver release. It adds "Perfect" mode back to options and fixes clouds corruption.
Just make sure the exe name is il2fb.exe

I have posted the info here

Thank you very much for taking the time and energy to bring that issue to AMD's attention.

I'm really looking forward to that driver release.

If i got more time i give it a try on my RX 7900 XTX, but i think on those cards it not just a OpenGL problem, since under DirectX it also has isues with the Hardwareshaders.

As far as I understand it, DirectX is just a wrapper on this game, so it runs OpenGL in both cases.

There have been 2 AMD Driver updates since this post. I'm running the latest stable version 24.3.1 and Adrenalin doesn't report new updates.
Today I installed IL-2 1946 and the game doesn't allow me to turn on "Perfect mode" and reverts back "Hardware shaders = 1" to "Hardware shaders = 0" on conf.ini every time I boot the game. Is the fix already present in 24.3.1 or am I doing something wrong?

Thank you very much in advance

I can confirm that as of driver 24.3.1 I am able to run Perfect graphics flawlessly on my 6950XT.

That being said, I tried changing the OpenGL portion to enable them initially and the settings would not take. In addition I had black oceans and various artifacting.

I reinstalled 1946 and UP 3.4, starting with a fresh config file and was able to set perfect graphics. I copied the [OpenGL] portion of my new conf.ini back into my old 1946 instance and it didn't solve the graphics issues. Copying the entire conf.ini file and overwriting the old one did fix the issues.

When using the new drivers it is important to revert to openGL in the conf.ini if you use directx you won't have perfect mode enabled
[GLPROVIDER]
GL=Opengl32.dll

Anyone who hasn't updated their AMD drivers for some time and who is still on 23.x or older, should update their drivers anyway:

I had the same issue with artifacting. It's strange. Did your vanilla 1946 allowed to set perfect landscapes? Or you checked only after the mod installation?

I confirm I was using OpenGL as driver backend.

My card is a Radeon RX 6600M

Thx in advance

I've just did a fresh install of IL-2 1946 and checked again I was using OpenGL as GLProvider.

I'm using GOG version on windows 11 in case it is important. I've tried out version 1.10 (Legacy beta channel) and 1.13 (no beta channel)

It just doesn't work for me. Perfect mode is greyed out. I don't understand...

The game runs great otherwise, solid fps. If I set the game to DirectX the cloud artifacting disappear, but I would like to use OpenGL and Perfect mode

Edit: Tried the Steam version as well to no avail

Hi Folks,

I ran into another snag while playing with my AMD drivers. I have a Dell laptop and am hitting the error below. Is it safe to say this is because it's a Dell that I am stuck? Is there any way around this? Sorry if this was asked before. I searched here but didn't find it.


Error 182 – AMD Software Installer Detected AMD Graphics Hardware in Your System Configuration That Is Not Supported

Possible cause - (Customized AMD Radeon™ Graphics for original equipment manufacturer (OEM) systems)

[Frankiek]

It seems that the only way around this would be to get GPU drivers from Dell support rather than AMD

[jg1234]

Thanks Frankiek. That is what I figured.

I have the conf file hardware shaders set to "1" even though in game the "perfect" option is greyed out. All in all, the game looks pretty good for my travel laptop needs.
