Your texture is also using more memory with no gain in quality. Data that's been uncompressed from a lossy format inherently stores useless information.
And that then eats into memory throughput & usage for no reason

good thing I don't use lossy formats

Hanprogramer•1/8/23, 1:44 PM

This is what I've been thinking of doing. Since that way it's easier to pack and I can automate most parts since i use a custom editor GUI app thingy. My game engine is 2d only for now and focuses on 2d. So i think i could do it in raw bytes yeah just for faster startup time (on final builds) but when in editor just load the raw PNGs or JPEGs or etc.

Hanprogramer•1/8/23, 1:45 PM

also most of my textures will be auto packed to single atlas or few atlases by the editor

Redhacker2•1/8/23, 1:45 PM

after all, if I am going to send an image in RGBA to the GPU, why would I create lossy versions of textures to store on disk

Aqua•1/8/23, 1:46 PM

because then you can upload it to the gpu in a compressed format so it uses less vram and gives a (slight) performance boost?

Redhacker2•1/8/23, 1:46 PM

not if I am going to uncompress it before loading it on GPU... like I previously stated would prefer to do...

Aqua•1/8/23, 1:46 PM

why would you do that though

AAqua is it decompressable on the gpu though? that's the *real* advantage of DDS and K...

TechPizza•1/8/23, 1:47 PM

factorio compresses its texture atlases :)

Aqua•1/8/23, 1:47 PM

there is literally 0 point in doing that

TTechPizza factorio compresses its texture atlases :)

Aqua•1/8/23, 1:47 PM

yea ive not seen compressed textures for 2D games but im assuming it can look okay

AAqua *why would you do that though*

Redhacker2•1/8/23, 1:47 PM

because I prefer having the textures in a format easily read on CPU and easily authored by myself

Aqua•1/8/23, 1:47 PM

bit like a jpeg

Aqua•1/8/23, 1:48 PM

you load in textures and make changes to them directly before uploading them to the gpu?

Redhacker2•1/8/23, 1:49 PM

Ideally yes. I would like to be able to stamp things on top of various textures

Redhacker2•1/8/23, 1:49 PM

or at runtime generate textures to use.

Redhacker2•1/8/23, 1:50 PM

I would also not like to have to deal with a dozen variously compressed texture formats

Redhacker2•1/8/23, 1:51 PM

and authoring said textures.

TechPizza•1/8/23, 1:51 PM

you are argumenting as if one is not allowed to compress textures at runtime

TTechPizza you are argumenting as if one is not allowed to compress textures at runtime 🙃

Redhacker2•1/8/23, 1:52 PM

I am arguing as though I don't want to deal with the overhead or dealing with compression/decompressing the textures at runtime

TechPizza•1/8/23, 1:52 PM

and the shaders get color values in the end regardless

Redhacker2•1/8/23, 1:52 PM

both in code or on my brain

Redhacker2•1/8/23, 1:53 PM

and it ain't that slow.

Aqua•1/8/23, 1:54 PM

just wait until you are using many 4k textures in one scene and then you will be thankful that gpu compressed textures exist

AAqua just wait until you are using many 4k textures in one scene and then you will be...

Redhacker2•1/8/23, 1:54 PM

I have no plans on doing so

Redhacker2•1/8/23, 1:55 PM

in most cases 4k textures are excessive, and also, that is why mipmapping exists

KaiOP•1/8/23, 1:55 PM

Even with lossless it can still be compressed. Then I suppose you're not storing redundant information, but it's still inefficient for no reason

Redhacker2•1/8/23, 1:55 PM

I am not arguing about CPU side compression

KaiOP•1/8/23, 1:56 PM

KaiOP•1/8/23, 1:56 PM

CPUs Support lossless compressed textures as attachments and sometimes even for reading from compute

Redhacker2•1/8/23, 1:57 PM

I am saying I would like to be able to actually edit and modify my image data on the CPU side, my big thing is authoring and having compression and decompression codepaths.

KaiOP•1/8/23, 1:57 PM

The only advantage straight RGBA memory has is writing

KKai The only advantage straight RGBA memory has is writing

Redhacker2•1/8/23, 1:57 PM

to which that is my main reason for wanting to stay in RGBA

Redhacker2•1/8/23, 1:58 PM

I also don't want to deal with decompressing various different compression formats to get the RGBA textures out

Redhacker2•1/8/23, 1:59 PM

nor a compression library to compress them initially

TechPizza•1/8/23, 1:59 PM

why would you want to edit any texture at any time though

RRedhacker2 I am saying I would like to be able to actually edit and modify my image data on...

KaiOP•1/8/23, 1:59 PM

I mean sure, if you need to edit it, I get it.

Furball•1/8/23, 1:59 PM

just edit the texture ahead of time

TTechPizza why would you want to edit any texture at any time though

Redhacker2•1/8/23, 1:59 PM

I want to paint

Furball•1/8/23, 2:00 PM

what

Redhacker2•1/8/23, 2:00 PM

no but seriously

Redhacker2•1/8/23, 2:01 PM

I do want to be able to make changes to textures at runtime, mainly for runtime level editing and texture design.

Redhacker2•1/8/23, 2:01 PM

I would like to keep everything in game or at least in engine if possible

TechPizza•1/8/23, 2:01 PM

gpu-compressed textures are usually trivial to decompress, but you do you

Redhacker2•1/8/23, 2:02 PM

I looked into it, and they swirrled me into a headache pretty much instantly

Redhacker2•1/8/23, 2:02 PM

or at least the DXT line did

TechPizza•1/8/23, 2:03 PM

they would not be useful on the gpu if they were algorithmically difficult to decompress

Redhacker2•1/8/23, 2:03 PM

not to mention they each seem recommended for different common usecases, meaning I would probably want I think it was to support the main 3. Which pretty much made me threw my fist up.

TTechPizza they would not be useful on the gpu if they were algorithmically difficult to de...

Redhacker2•1/8/23, 2:03 PM

I never said anything about being algorithmically difficult

RRedhacker2 I looked into it, and they swirrled me into a headache pretty much instantly

TechPizza•1/8/23, 2:04 PM

really now
