performance issues

[hiban1]

Im using this but the game is lagging, if there is too much lights I'm modyfying the global_lightning function but its not enought, I guess the shader is very recursfull

Hey there idk if I'm late or not but I have a fix for your performance issues.
Go to sh_shadow_map.fsh

and change these like this
#define BLEND_ITERATIONS 4 // 8
#define BLEND_TEXELS 32.0 // 64.0
I put a comment for the default value so you can revert it or just use undo...
I know the shadow or lighting will feel a little odd but trust me it's better.

Tell me if your game now runs better with these changes.
Oh man I just hope the Authors come back...

Yes I've done it but it doesn't change anything, all I know is that it's comming from the lights because when my camera is in the shadow nothing happen, or maybe it's comming from my computer because I don't have a dedicated graphicall card but when I test the project on his own and not in my game it works well...

[DevTRUCKer]

hmm... yea I think the issue from your computer OR I still also feel it's from the lighting system itself because it did not get updated for so long time so maybe it's not compatible a little with your GMS version, idk your GMS version, if you are using "Monthly" or "Beta" maybe try the "LTS" version in a separate project.

Also, I have a suggestion, and I know it still will not do anything but did you change the in_TexCoord to in_TextureCoord in the two shaders? check this (#7)

So yeah, I don't have any other suggestions the last thing I can tell you is... (nope not upgrade your PC) it is you can give me an example project with the same lights and shadows to see if my PC too can handle it.
Yep, that's it I hope you find a solution SeeYa.

Ok I will try next time because I have a lot of things to do on my game. Hope I manage to do it, it will bring a lot...

Suggest!
You can use beta with the new GMRT if you don't have but Please backup your project first.
GMRT focuses on Performance so your game may work better with it but if any errors show up you may work again on whatever version and runtime you were using.
