gpu

I'm trying to use Iris with shaders in a modpack, and while the game runs well enough, I've found that while my game runs on the GPU, my shaders run on my CPU for some reason, which isn't what I want. Is there a way to make sure that the shaders run on the GPU?

Iris help

I downloaded iris and its a jar file, but what do I do from there

Bug

I've been running project luma shaders through iris shader launcher (1.20), and I ran into a bug where upon entering nether, my game screen split into 2. Smaller window on the bottom left of the cursor and other one behind it full screen. Both display the same thing mostly, exept the larger window didn't display the purple thing inside the portal. I tested turning shaders off and everything worked normally. How should I fix it?

Chat, Scoreboard and Tab(Player list) is dark with 1.20 Fabric.

I updated to 1.20, but the chat, scoreboard and tab is so dark. Without shader, it's normal. I tried some shaders, but they have same issue. Client and Launcher: Feather Client...

Odd bug since switching to Minecraft 1.20

Everything still works except the chat frame is darkened when using Iris. I've tried using several different shaders, the darkened text is still like that. The screenshots are comparing shaders enabled and disabled.

Weird Issue With Shaders Like ApolloRT and NostalgiaVX. (1.20)

I'm having this issue where NostalgiaVX has no shadows casting or direct sunlight, and with ApolloRT and NostalgiaVX where if I am far away, the lights seem to render, but when I get close, everything is black. No shadows, no light bouncing or anything. Idk if this was an already addressed issue or not, but I couldn't find anything about it....

Iris Installer 1.20 (Mac)

(I am on Mac) Hi I downloaded the Iris automatic installer off the Iris website (that's in the links section of this discord) and it won't open. It comes up "Unable to locate a Java Runtime." Does that mean I have to install Java separately for it to work? Thanks....

Having really odd memory issues with shaders enabled

I'm having a really bizarre issue with iris, and I've been trying to find the cause of this issue for a week. When I have iris disabled, my RAM usage sits around ~13 GB, even when in creative and generating new chunks. However, if I enable shaders, after a few minutes my RAM usage continually rises until I disable shaders. I've found some github issues that are similar to what I am experiencing: https://github.com/IrisShaders/Iris/issues/1862 https://github.com/IrisShaders/Iris/issues/1862...

Iris support for custom core shaders in mods

I am writing some core shaders for some blocks in my mod for 1.20 MC. Someone just came to me and pointed out that Iris will explicitly not render my shaders at all and make my blocks invisible. Is this true? And if so, why was such an incredibly limiting and handicapping decision made? These core shaders are pretty critical to the new blocks I am adding and without them, I cannot achieve the end vision I desired for my blocks. And I don't have the ability to make a brand new Iris specific shader as I could barely get by making just these core shaders with lots of help from others. An Iris specific shader would be over the limit for work I can do...
