need some help with GzDoom

[Jerememes]

So, I use a low-end pc to play doom sometimes, whats the lowest graphics I can set GzDoom to, and how can I do it.

"Low end PC" is very unspecific. How old is it?

GZDoom should work fine on everything that was sold in the last 10 years, if it has a discrete graphics card on everything that was sold in the last 15 years.

its 'bout 5 yrs old but runs like shit most of the time, also its a laptop, so it can't use a graphics card.

A five year-old laptop should still be at least able to run it.

 

But well, the simplest is, well, simple. Disable stuff like brightmaps and dynamic lighting. Don't filter textures (or if you do, do it only with light stuff like trilinear filtering). Lower the video resolution.

 

If you know the model of the laptop, or run some sort of program like Speccy and put up the results, we can tell a lot more about it.

The easiest way would be to just start GZDoom and look what you get. With low end graphics hardware the best way to get a bit more performance would be to lower the screen resolution to minimize the amount of data to be rendered.

 

Disabling brightmaps won't really do much. Texture filtering is not a performance issue in general, but on memory constrained hardware it may help to choose a filter mode that does not use mipmaps, but that's only really an issue for larger projects. Disabling dynamic lights can help, though.

 

But no matter what, if you know the computer has bad performance, better stay away from larger maps that may push the engine.

Try different backends. Depending on your system you may get better performances with Vulkan, OpenGL, or OpenGLES.

You could always try LZDoom which is more lightweight.

Maybe this will help
