the rendering quality setting has no effect

Post by drfrag »

I don't know if this is a bug or not, probably not, but i've noticed that on the GL 2.1 legacy render path you cannot enable the quality rendering mode. That CVAR has no effect and i always get the speed quality level, this happens at least on my old ATI card. BTW i guess 1.9.1 should be much better on my system (with those 1.2 shaders) but i don't notice much of a difference besides the mentioned problem.

If my memory is correct about what the Quality setting actually does (i.e. helps get rid of "poly gaps"/white dots in map geometry), then I can confirm that having it set to Quality does nothing for me. Relevant information about my video card from Speccy:
NVIDIA GeForce GTX 1060 6GB
Manufacturer NVIDIA
Model GeForce GTX 1060 6GB
Device ID 10DE-1C03
Revision A2
Subvendor EVGA (3842)
Current Performance Level Level 0
Current GPU Clock 139 MHz
Current Memory Clock 405 MHz
Current Shader Clock 405 MHz
Technology 16 nm
Bus Interface PCI Express x16
Temperature 50 °C
Driver version 22.21.13.8205
BIOS Version 86.06.39.00.60
Physical Memory 2047 MB
Virtual Memory 2048 MB
And for reference, my testing has been with GZDoom stable version 3.1.0.

Last version with the option working for me was 1.9.1, not working on 2.2.

I've done more testing on a Geforce 7300 with OpenGL 2.0.3. Still no difference on GZDoom 2.2 but now the game always looks good while on my ati card (radeon x1250 and GL 2.1.8) always looks bad (with the dots). On 1.9.1 it's the same, there's no difference here (the switch worked on my ati card).
I still don't see much of a difference between the two versions on this card (with or without shaders).
To clarify things a bit the switch doesn't work on 2.2 and later versions on my ati integrated video.

I can confirm at least on my GTX 770 that the quality option is working, but not as well as it used to be. With older versions of GZDoom, I've experienced no issues what so ever. White pixels are frequent with the Quality setting, but not as much as Speed.

Computer specs 'cause reasons:
Windows 10, Creator's Update (Up to date, as always)
Intel Core i5 3570k @ 4.2GHz
12 GB of RAM
EVGA GTX 770 SC
NVIDIA Driver Version: 382.33

I can confirm it works with 2.2 on my Radeon HD 4650 with GL 3.3 support.

This works with Legacy mode, last I checked. in fact, toggling it helps remove the "polygon fan" medusa bug I was experiencing.

Fixed. This was just one little missing '&' in a variable declaration that caused the info to be written into the void... :(

Sorry Graf, it's hanging around in my case:

It looks identical with either Speed or Quality. I'm on a Mac if that matters...

It is g3.2.5a with an NVIDIA GeForce GT 755M 1024 MB. Hopefully relevant?

How can the fix made January 21th appear in the build released January 6th?

When I read of the fix I immediately went to https://zdoom.org/downloads and downloaded the Mac version. I just downloaded it again- still has white spots...

Oh it still says 4th of Jan above the link??
