OpenGL Hack Bloom in GZdoom (Continued Discussion)

[cortlong50]

I'd kinda prefer for all this shading to be done engine-side (it would be less OS-dependent, and maybe perform better). Perhaps I should make a fork of GZDoom with custom shader support.

I triple dog dare you.
Because there's no way bloom should be as taxing as dynamic lighting.

So once again. TRIPLE dog dare.

Well, depends on how it's implemented. I bet it doesn't even use a downscaled screen copy for the bloom texture. Now THAT would explain the bad performance.

Edit: Browsing through code I've noticed GZDoom seems to have support for user-defined shaders, but I can't quite figure out how to add them in.

Shaders are only per texture. There are no postprocessing shaders - and the texture shaders are rather limited.

Wat. I just tried the 'fixed' version of the DLL file and this happened.

Hahaha. Well that looks good.

Well, seeing as you don't really use FBOs for anything other than camera textures I could hook up something for screen-space shading.

do it. and then make it so it doesnt strangle the life out of my pooor little gpu

where did you get this version of the DLL from ? What is your reference?

i really like this but it lags like crazy...any solutions to this problem or is it just my computer

This is super Graphics card heavy. For one because it kinda sucks and doesn't seem to be optimized. And also because you're throwing something that is recreating the scene in the game a bunch of times behind the scenes and when you're running multiple versions of the same scene on a card that really isn't made for that...well it'll definitely slow down. So it's probably your computer just sucking. Don't worry. This little thing kicked my computers ass too. This doesn't even seem to be an option unless you have at least a gig of VRAM.

[SyntherAugustus]

What card are you using to try to run this?

[cortlong50]

I'm running my on board ato Radeon something or other in my laptop. I literally don't even know what it is because it only has 512mb of VRAM and isn't nice. Dynamic lighting beats it up. TUTNT isn't even an option haha.
I keep heavy computing for my had 6770. Not the nicest card but a solid gig of ddr5. It gets the job done.

Wait. Does this post processor work with zdoom? I only tried it with gzdoom!

[cortlong50]

Never mind the last part of that as it's just straight dumb.

[SyntherAugustus]

ATI/AMD cards have alot of trouble with OpenGL. Possibly not with newer cards, but the older stuff would barf in OGL while Directx would run fine.
