I have a problem

Hello! I have a problem. I downloaded iris, I launch the shaders, but they don't work. Help me please. I used minecraft 1.16.5. On Mac OS

Worse perfomamce compare with Optifine ( -20 FPS with iris and with shaders)

For example, when i use SEUS PTGI HRR 3.0 shaders, i get 65-70 FPS with Optifine, but when i use Sodium + Iris, I get 30-40 FPS. I tried to Update my GPU driver, to reinstall minecraft, to use Simply Optimized modpack and etc, but nothing helps. Please guys, help, i cant play with forge and optifine. I turned off msi afterburner, tried to use different shaders, made sure that V-sync was turned off everywhere, installed ImmediatelyFast, nothing helps using optifine i got 140 fps with BSL, 135 fps with complementary, 450 fps without shaders...

Giant stretched-out black triangles glitch

Hello! I'm deving a mod called Mirage. Recently I've switched to using VertexBuffers to render fake structures but I came across this bug whenever I enable shaders: Is there anyway I can change my code to work with yours?...

V-Sync doesn't work on Iris

Vertical sync doesn't work with Iris even after enabling it. It gets worse as framerates get worse.

I installed iris for 1.20.4 directly from the installer, and when I try to play it gives me this error code from fabric. It says sodium requires indium, but when I try to add indium it tells me indium requires sodium.

black block breaking animation

Hi, I'm familliar with the black block breaking animation, and I know it isn't fixed yet by the iris team. Is there a way I could edit an existing shader (sildurs enhanced) to fix this?

Weird and glitchy skybox rendering

Hello, I've just installed Iris on fabric, and I'm using Chocapic 13 V9 shaders Low. Whenever I try to use a shader, the sky looks something like this. When I move the camera, it adds even more of the closeby texture on my screen. Disabling shaders fixes the issue. WHat should I do to fix this?

1.20.4 incompatibilty with essential mod leading to crash when loading world

Hello, so i decided to transfer my 1.20.1 modpack to 1.20.4 and noticed that the game would crash each time i would try to enter a world. At first it caught me offguard, because the modpack was compatible before the transfer so i decided to have a look at what caused the crashes I am using the latest version of fabric(0.15.4), esentials and iris(1.6.14) for fabric 1.20.4.

Destroying animation is too black

Hello ! I wanted to get the same result as OptiFine's internal shaders on Iris, because I prefer Sodium. So I installed a shader called "Fabulousity-r1" which imitates the new OptiFine internal shader lighting perfectly. My only problem is that the destroying animation of a block is very ugly and too black... On Optifine's internal shaders, it doesn't do that at all....
