TDM v2.10 unable to initialize OpenGL on laptop w. MX150

[geegee]

Asus i5 zenbook with MX150.  

Opened my WIP in the laptop to check and compare framerates against my i5 desktop with geforce 1060.  Since I'm using the dev build 16269-9407 on the desktop, used the same build on the laptop and got "Unable to initialize OpenGL" screen.  

Backtracked thru' the dev builds and found the last working version was dev16225-9284, which loads the game fine.  Problem starts with dev16238-9330 and the two newer versions.

No similar problem on the desktop.

(and.... WIP framerates on the laptop will give some people heart attacks.  Tho' I find it still playable - TDM isn't deathmatch - and it looks very good on that little machine.)

Maybe it is again the problem of choosing between Intel's integrated graphics and NVIDIA discrete GPU?

I don't see anything obvious in changelog which could break OpenGL initialization.

1. The first thing to check is which GPU the last 'good' build is using (e.g. via the Task Manager)
2. What are the screen resolutions on teh desktop and the laptop?

1.  opening TDM, prior to mission loading:  GPU 1 - copy (nvidia)

    after mission loaded:  GPU 1 - 3D (nvidia)

2.  laptop:  1920x1080

     desktop:  3840x2160  (a cheap LG TV - good for my failing eyesight, esp. when mapping, but looks like washed out crap compared to the crisp clear color of the laptop)

nvidia control panel can allow me to choose "preferred graphics processor" but ignores that when loading games.

Thanks

The same build that fails on the laptop still works OK on the desktop, right?

Laptop is running Windows?

I could try my nVidia laptop later this weekend, but can you try the latest drivers from Intel, nVidia, and Asus website in the meantime?

Ah, and also try changing the r_glCoreProfile to 0 in the .cfg

It's fixed - by updating the intel gfx with the intel drivers at the Asus site.

I had thought, since it was using the nvidia chip, that updating the nvidia drivers would be enough.  But I guess that "GPU 1 -copy" also addresses the intel chip.

Thanks, and I apologize for wasting your time!
