Bouncing torches/candles and 2 more

Postby filipetolhuizen » Mon Jun 29, 2020 4:34 pm

Hello,
I'm using GZDoom 4.4.2 64 bits build and I noticed that all fire animated sprites keep "bouncing" up and down in all games I tested (Doom, Heretic and Hexen). I'm using True Colour SW Rendering and trying different scaling options didn't fix it.
This other one I'm sure it was asked before here, but I was just wondering if a definitive fix was found: sprites above a ceiling or below a floor are visible despite being behind it (most noticeable, a barrel on Doom2 E1M2).
The last one is a minor thing: If I change anything related to the rendering, the game starts to "hiccup" and I have to switch to the Vanilla rendering to make it stop, or quit and run it again.

I think the first issue is a duplicate of this bug:
viewtopic.php?f=56&t=68042
I remember reading something related to the second one for the SW renderer.
About the third one please elaborate, with vanilla you mean SW?

Exactly, but it's not limited to Heretic.

Yes, but I didn't try much of the hardware rendering because it runs too slow on my system, at least with the same eye candy turned on in SW.

SW mode, truecolour renderer. The hiccups stop if I quit and restart or switch to 8-bit classic renderer.

Change sprite clipping mode and see if it fixes the bouncing.

The bouncing happens in the Carmack software renderer and i can't fix it, only dpJudas or randi could i think. It's not that bad tough and i've noticed it also happens in the hardware renderer at extreme horizontal/vertical angles. I also noted in that thread it happens with Doom torches too.
The first two issues are duplicates the third is too vague. Which rendering options? HQ resize mode?

Yes, the bouncing happens with Doom, Heretic and Hexen torches. Changing sprite clipping mode makes no difference.
3rd issue happens with Truecolour software renderer, with or without hq resize modes whenever I change any rendering option, but if I quit and restart the game, it's gone, so it's not critical.
