GZDoom "R_OPENGL: OpenGL driver not accelerated!" Intel/w10

First, you'll need to download one of these GZDoom builds here: http://devbuilds.drdteam.org/gzdoom/

After that, extract it to a folder and place any doom wad/wads you wish in the same folder. Then you want to download this: https://github.com/alexey-lysiuk/tools/ ... fi/Release

Place it in the folder you extracted GZDoom and drag and drop the gzdoom.exe file on the wtfi.exe file:

A window will open and quickly ask you to press any key to continue, do it! There you go, you now have a working/patched version of GZDoom!

:bfg: :angel:

So, a little update here, you don't need to use one of the GZDoom builds mentioned earlier, you can use the latest GZDoom update (v2.2.0) too: https://gzdoom.drdteam.org/page.php?page=download
Just make sure you download the 32-bit one, I have a 64-bit system but the 64-bit one doesn't seem to work, okay?

This may or may not need some form of addressing for those who use ZDL.exe. Just saying. I don't personally have this problem, but it wouldn't hurt to provide a workaround for those who use launchers. (I would say if I knew of a good workaround myself, but I do not.)

wtfi.exe is a patcher tool that rewrites the manifest. It only needs to be run once (per devbuild/release) on the .exe and then ZDL will launch it just fine.

Works for EDuke32 as well though you have to select the .exe file manually.

It works, but with some mods cause gzdoom go on background (mouse cursor appears and music is still playing).
Is there any solution for this problem?

I don't understand your question. Are you using Google Translate? Can you ask in your native language? There may be someone here who can understand you.

This tool is great, but with certain mods it causes gzdoom to freeze.
I did some investigation, and I found out, that it happens whenever a 3d model (from MODELDEF) is used.

If you want to load a mod with 3d models (like brutal doom, project brutality, russian overkill...), you can try this fix:
https://pal1000.github.io/shared/tutori ... -win10.mov
which works for more opengl applications.

I've applied this method to several different recent versions( gzdoom 3.2.1, 3.2.5, and SVN ver g3.3) and all of them still say
"R_OPENGL: OpenGL driver not accelerated!"
What causes this anyway? Ver 3.2.1 used to work for me and now it doesn't, and my computer hasn't downloaded any updates recently that i can see that would affect this.
I too also use ZDL( not for trying this fix mind you) and would like an answer to this issue as well.....
This just boggles my mind.


Edit: Reinstalled all of the DirectX components and it fixed the issue.

So...weird issue. I go load up gzdoom for the first time today and it gave me the driver is not accelerated error. Problem is I had done the wfti.exe fix already several months ago, and up until yesterday it was working fine. Redownloaded gzdoom and did the fix again but it didn't work. Display driver has the most up to date driver. What can I do to get it working again?

For context, I'm running laptop with Integrated Intel gfx and win7 32bit, laptop is several years old. Thanks in advance.

a better option than patching gzdoom is to use an updated version of OpenGL
since patching it can be executed but without being able to use any of the OpenGL features.

I have a patch that worked for me

link OpenGl 4.0 and 4.1:

http://www.mediafire.com/file/zbyzk8nsl ... GL+fix.rar

https://www.mediafire.com/file/yrf6gtka ... nGL+fix.7z

n my case I have:

Intel i3 M350 2.27 GHz with intel HD Graphics.

and Windows 10 Single language 64 bit.

Please do not post such things without knowing what they actually do. This in no way 'fixes OpenGL'. It's an entirely separate software based implementation that is very likely to be a lot slower than what it replaces. Patching the EXE will ensure that it works with the native driver.
