Debug vram usage?

[InfernalGrape]

Hi. Lately I've been using hidef textures/sprites, so I wonder if there is a built-in display option in GZDoom (or even in Doom Builder?) to show current vram usage.

Is there such a thing? Would be weird if there isn't.

So, uh, no way to check how much memory hd sprites and textures take up?

I mostly use 1000 px height sprites for stuff like monsters so I worry if I gonna overload the game with HD content.

I am not aware of an option to do this inside GZDoom. Does not mean it does not exist, only that I am not aware of anything.

 

You may be able to get information from the OS or a video card program. For example: I can see resource usage including VRAM in Windows' Task Manager's performance pane. I can also see resource usage in EVGA Precision, since I have an EVGA graphics card (RIP).

 

Unfortunately, neither application provides per-process information. However, it should be close as long as there are no other games or other programs running that store textures in VRAM.

 

Unless you have WAD files with literal gigabytes of texture and sprite data, I seriously doubt you will bump up against the memory limits of any graphics card produced in the past three or four generations. I just performed a quick test and loaded up a WAD with custom graphics, and it bumped VRAM utilization from a baseline 2,587MB to 3,005MB.

 

Even if you have an older card with 4GB, that is still only 75% VRAM utilization. Some of that baseline is also likely to be allocated by system processes but not actually used for anything. If a game needed that memory, it could probably use it.

 

I seriously doubt that VRAM usage is a big deal for GZDoom unless you are using a very old graphics card.

Hi, thanks for reply.

Yeah but that won't show you stats during play... Guess I need to find tools that can do it while having overlay on top of any game. Hm...

My main PC is from 2015 (with 4 gb vram gpu), but I also have 2011 era laptop (with 1 gb vram dedicated gpu), so I tend to try my projects on both. 

 

Though I must admit, I have an idea of making "less resolution" versions of sprites for "low end" machines as it's easy to swap around.

 

But yeah, let's imagine I would try to make a standalone total conversion release - for such, I would like to be able to provide more or less "believable" system requirements for other people to know.
