Contrary to popular belief, we are not all-knowing-all-seeing magical beings!

If you want help you're going to have to provide lots of info. Like what is your hardware, what is your operating system, what version of GZDoom/LZDoom/whatever you're using, what mods you're loading, how you're loading it, what you've already tried for fixing the problem, and anything else that is even remotely relevant to the problem.

We can't magically figure out what it is if you're going to be vague, and if we feel like you're just wasting our time with guessing games we will act like that's what you're really doing and won't help you.

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?

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.

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.

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.

I tried using wtfi.exe to fix my problem with GZDoom 3-4-1, but it, er, didn't work. Doomworld user Gez said (here: https://www.doomworld.com/forum/topic/8 ... nt=1641369) that fixing the problem is supposed to be as simple as drag-and-dropping gzdoom.exe onto wtfi.exe, but when I try, I get this message:

> ERROR: EndUpdateResource() failed for file c:\users\\******\Downloads\gzdoom-bin-3-4-1\gzdoom.exe with code 0x00000005

> press any key to continue...

Elsewhere I've seen
Any idea what I'm doing wrong? Thanks in advance!
