KVELLER Posted January 16, 2018 It seems to be a common issue, even though I don't know if there's a way to fix it. Personally I just got used to it. Also, this should've been posted on the "Source Ports" section. 0 Share this post Link to post

VGamingJunkie Posted January 17, 2018 Is VSync on? Sounds like graphical tearing. 0 Share this post Link to post

VGamingJunkie Posted January 18, 2018 Well, that's the only thing I thought of that sounds like this. 0 Share this post Link to post

Cacodemon345 Posted January 18, 2018 It seems to be a issue in NVIDIA GPUs. AMD GPUs work fine. I myself didn't encounter any white dots/pixels on my AMD Radeon RX 460. 0 Share this post Link to post

Well, I'm playing with Intel HD Grpahics 630 :P I'm wouldn't really be surprised if that's causing issues. Also: Quote 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) 0 Share this post Link to post
Cacodemon345 Posted January 18, 2018 ATI/AMD laptop GPUs, along with Radeon HD GPUs are shit, powerful RX series desktop GPUs aren't. 0 Share this post Link to post
Reisal Posted January 19, 2018 Try turning FXAA on (low setting in your case, I use medium because RX 480) because once I did this, I didn't see the white "edges" 0 Share this post Link to post
Cacodemon345 Posted January 19, 2018 I use High FXAA setting. @RetroDoomKid,you use low FXAA. 0 Share this post Link to post
KVELLER Posted January 19, 2018 Personally, I rather have some white pixels than a blurry image. 0 Share this post Link to post
DutchDoomer Posted January 19, 2018 also there is no option in zandronum that has fxaa.. and even if it set it to quality it still there.. as for gzdoom i fixed it by turning on multi to 4x but still id like to keep it off but then i get those dots is there not a way to fix this? does this happen on like every computer mostly? its rly bothering me its especially bad in plutonia dots everywhere! it almost looks like graphical issues like artifacts but since a lot of people are getting this across the board i bet its not a related to a faulty gpu so not sure now 0 Share this post Link to post
Reisal Posted January 20, 2018 Yeah, I meant GZDoom. Should have clarified. 0 Share this post Link to post

If problem still happens then I don't know. :( On 2018/1/18 at 10:10 PM, Cacodemon345 said: It seems to be a issue in NVIDIA GPUs. AMD GPUs work fine. I myself didn't encounter any white dots/pixels on my AMD Radeon RX 460. Maybe, but update the driver maybe fix it, at least it's not happen on my GTX 1060. anti-aliasing 32x + max FXAA, seems perfectly fine. :p (But I'm using 368.81 driver, from 2016, don't know if latest one would cause any problems like this, but older ones may.) 0 Share this post Link to post
Sinael Posted January 21, 2018 (edited) It has nothing to do with FXAA, nVidia GPUs or AMD GPUs, drivers or anything like this. It's a Rendering Quality issue. GZDoom has 2 methods of rendering - high precision and low precision. Lower precision obviously means higher speed, but the cost is that sometimes white dots appear on texture seams. https://zdoom.org/wiki/OpenGL_options Setting "Rendering quality" in Opengl options to "quality" (or gl_render_precise to 1) in THEORY should rid you of hte artifacts in question. The problem is, since GZDoom 3.0 the feature does not work and only low precision rendering is available. Zandronum should still have it working though, try setting it on and see what happens. 1 Share this post Link to post

Looks like dpJudas's spotlights code also got merged. Means soon we'll be getting some more advanced dynamic lighting options and actual flashlights that aren't a string of light actors. 0 Share this post Link to post
