This setting in gzdoom gives the bets fps boost!

[Perplexity]

If you want to increase your fps massively in gzdoom, just decrease your scale factor. It gives me a big performance boost, some downsides to this are the fact that everything looks way more pixelated, also the text becomes bigger. But you can just convince yourself that this is an "art style" inspired by psx graphics, right? You can decrease it depending on how much you tolerate the pixels, my sweet spot is 0.5.
Here's an example:
This is with scale factor set to 0.5


Meanwhile, this is with scale factor set to 1:


As you see it gets mor epixelated, but it is more faster. By the way my fps is capped to 62.

or you could just...y'know...turn off all the effects...

Are you using software rendering or hardware-accelerated rendering? Software rendering is highly dependent on resolution (which is what you're adjusting), but at least for me adjusting the resolution hardly makes a difference when I'm using hardware rendering (my guess is that since my CPU is much older than my GPU, when I do lose frames it's bottlenecked on CPU operations that are independent of resolution).

This, is right, but this one is also a good way if you want to keep the effects while still having good performance, of course more details will be lost, but yeah.

Huh, weird, I use hardware accelarated rendering and opengl, but for some reason it increases performance for me, probably because I have an integrated gpu? I don’t know to be honest, for now I will keep using 0.5 scale factor unless my fps is still decent.

Or you could be a based boomer and play with 640x480 35fps software rendering
