TOPIC: [SOLVED] IL2 1946 SetPixelFormat issue.

IL2 1946 [OpenGL] SetPixelFormat issue. 3 years 2 months ago #1

Hi Crosire,

Really old OpenGL engined flight simulator is failing to start with ReShade. Log indicates invalid pixel format when createcontext is called.

Game uses 32 colour bits, 24 depth bits and 8 stencil bits.

I know it's a case of diminishing returns to keep catching and creating workarounds for ancient game engines especially when it seems that ReShades goal is to be a generic framework, but this was the game I tested reshade on so here's the bug report.

Mind also posting the tracelog (or its part around "SetPixelFormat", which prints out some more info about the problematic format)? =)
Cheers, crosire =)

Using an nvidia card which supports OpenGL 4.3 and drivers support 4.5.

Would be interesting to see if it's that particular pixel format (though I'd be surprised, the properties with which it was requested are quite standard), which is the problem or something else. Mind getting on Steam? I'd send you a build which forces a different pixel format for testing and some other small tweaks ... =)

Has there been any further development of this issue? I am encountering the same issue when trying to utilize ReShade for this title.

Yes, I have a fix for it, but I'm not really happy with it yet, which is why it didn't make it into 0.15.0.

Alright cool, what should I look for in future change logs that will indicate the solution is included? Thanks for your efforts, and good luck with future developments. Looking forward to using ReShade in this game!

Update on this: Finally fully figured out the "why". For anybody interested: the game calls the undocumented "wglSetPixelFormat" directly, where it actually is supposed to call GDI "SetPixelFormat". This caused the context creation to fail. ReShade 0.16.0 now reroutes these illegal calls back to "SetPixelFormat" and by that fixes the issue.
