Upgraded to 4K monitor... [Solved]

[princetontiger]

... and GZDoom isn't buttery smooth anymore. My resolution is higher, too. I was on a 1080p monitor previously.

 

Video settings: Doom Software Renderer and OpenGL.

 

Any suggestions?

 

EDIT: GZDoom automatically adjusted my gaming resolution to 3840x2160. I had to manually toggle this back to 1920x1080 since I'm using 200% scaling. GZDoom looks and plays beautifully.

I mean internal resolution gets increased ofcourse from 1080p to 4K. So on the software renderer that is obvious.

 

What's also obvious are some missing details:

• Which version of GZDoom are you running
• What are your PC specs
• Are you running any mods
• What constitutes buttery smooth in your book. This is incredibly subjective

So lower it. Software rendering performance is highly dependent on resolution.

[princetontiger]

Yikes. No more fullscreen for me.

 

After some research, it appears that GZDoom exhibits substantial" lag" (lower frame rate) as I increase the game resolution.

You can lower the rendering resolution while staying in fullscreen.

Well yes, it does indeed eat a lot processing power.
I have low Tier GPU, and when I want to play Smoothly I reduce the Desktop Resolution when using GZDOOM, my Screen is 1080p
but I have some slow downs with that resolution, so I go down to 1600x900 in gzdoom and with That I play smoothly at 75fps.
If your Screen allows the use custom resolutions in your GPU settings (Either NVIDIA or AMD), make a custom resolution in the same aspect ratio as your screen and play, it seriously doesnt look so bad as when you decrease the resolution on desktop, and then Open GZDOOM matching the same resolution and play in full Screen.
Lets say you decrease it to 2K, that might work best for you since the pixel density of your monitor is higher.

gzdoom stays between 300 and 600fps for me at 4k with a weak card (1660S) using vulkan/hardware acceleration.

[princetontiger]

I tried a bunch of different settings. And I was able to get Doom to play nicely when I brought down my game resolution to 1440p.

It's very funny that you think listing your OS, Monitor and Resolution is the same as listing your specs, but that's ok.

 

Anyway, I saw your post before you edited it, and your main bottleneck is your Render Mode setting. Your Rendering API may be set to OpenGL, but as long as you have your Render Mode set to "Software," you will not be able to get decent framerates at 4k, as software rendering scales almost linearly, meaning that going from 1080p to 4k takes four times the power to render.

 

In GZDoom, there are ways to render at a lower resolution (like you do now, seemingly), and keep the image sharp, you just need to make sure your render and output resolutions are equally divisible and disable "Texture Filter Mode" to None—that could enable to to run the game at 1080p without the image looking blurry. The other option is to just use the Hardware Accelerated renderer.

 

[princetontiger]

I'm on a macbook air... by the way, I set the texture filter mode to none, and I do see even more improvement.

 

I'm going to keep Doom software renderer. The hardware one makes the game less smooth, and the truecolor renderer makes a tiny change to the colors.

Which one? What CPU does it have? is it one of the new Apple Silicone ones, or an older Intel model?

I am very confused.

 

Also, the Hardware Renderer should not make the game less smooth, it should actually make it... more smooth. Unless your macbook air has a very, very weak GPU/APU. In any event, glad you are getting playable framerates, have fun.

It's been a decade since I've cared about computer specs... Attached is my 'rig'.

If you want to keep using the software renderer, you might be able to set GZDoom to use 1080p-like pixel density by going to the Get Info window in Finder and checking "Open in Low Resolution". If that option is there, it should allow you to have a larger game window without blowing up the CPU.

[hobomaster22]

At 1080 your GPU has to process 2,073,600 pixels. Your monitor upgrade pushes the number up to 6,868,800 at full resolution. GZDoom has a lot of processing in the shader that is going to drag the frame rate down on a mobile Intel card. If you really want to use GZDoom at the full resolution, your best bet might be using the OpenGL ES option. Assuming it still trims down branching and junk in the shader. Also, are you using vid_fps 1 in the console to confirm your framerate on any changes you are doing?

If you ask a technical question, why do you get indignant when people ask you for technical details?

Considering you only have an integrated graphics solution, your best option is to just stick with a lower rendering resolution and let GZDoom upscale it to native, as you seen to be doing already.

 

like The Hobo-Master™ said, going from 1080p to your stated 3180x2160 resolution more than triples the number of pixels your system has to process to produce a frame, so the frame drop is to be expected. Also make sure you are running your monitor at it's native resolution the S2722QC has a 3840x2160 panel (16:9 "4k"), it shouldn't impact performance, but the image may be stretched or letterboxed if you're actually running at 3180x2160.

[princetontiger]

Thx for the advice...

 

I have my viewport set so I don't get stretching or letterboxing...  I get a really nice wide view of a room.

Should be even easier than that, under scaling options in GZDoom is video mode scale factor.  Setting that to 0.5 would give 1080 with a 4K display.

Ah, even better :) I should've checked first!

Guys,

 

I figured out my issue. I had more time tonight to investigate.

 

While I am using a 4k monitor, macOS scales me at 2x... so, I see 1080p. It looks amazing, by the way. Anyway, GZDoom automatically set itself to the 4k resolution, but in fact, I am at 1080p. My macbook air was trying to play a 4k resolution setting while on 1080p. Obviously, major slowdown issues. Once I set my resolution to 1080p in GZDoom, I got buttery smooth gameplay.

 

Below are my settings, and the game plays WONDERFULLY.

I'm not sure exactly what it does, but it might have something to do with the "Retina/HiDPI support" setting that you have set to "yes" in your screenshot.

[princetontiger]

What initially tripped me up is that the resolution of all my screenshots is still outputed at the 4k resolution of 3840x2160... however, I'm 2x scaled in. I have screen real estate of 1920x1080. macOS, by default, will display at 2x scaled on 4k monitors.

 

Talk about a crash course into all this uhd/retina/pixel density advances over the past decade.

I always use the lowest 16:9 resolution available. It's Doom, after all.
