Help with Renderers lagging

Forum rules
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.

Yes. A Intel HD4000 should better just run the GLES renderer at best. This is coming from someone who has a HD4600, which isn't that much better.

Either that or use Helion but you loose out on GZDoom exclusives.

Alternatively. Windows might've installed its own drivers - which has been known to do. Reference this website and grab your latest drivers, see if that fixes anything. It might even give you the option to download an older driver if the newest doesn't work.

Alright, thanks.

Most likely, unfortunately. Try updating the drivers, if you haven't already. :)

A Intel HD4000 is really just the bare minimum. Im on a Intel HD4600 myself and ill just make sure i either use OpenGLES or set everything down real low as to not impact the perf too much.

FWIW, Hands Of Necromancy runs fine.

It's fixed itself somehow, I can run on opengles fine now and the long loading times are gone.

We need to know what mods you are loading and also the specs for your system.

I had this problem that started yesterday, whenever I use Gzdoom on a renderer that isnt OpenGl specifically it will lag a lot in every frame. Except for the pause menu and such. The problem wasn't there prior and before it started I could use Vulkan, OpenGLES without issues and with much better performance. This happens on any version above 4.10 also, and now even with opengl load times take long, from the results screen to loading any save and from map start.
