Used Iris+Fabric for install, but it says theres no Fabric installed.

I just installed Iris, and I intend to use it with a couple other fabric mods, so I hit the Iris+Fabric button. When I try to load the game though, it says a couple of the mods (Double Doors and Collective) need fabric and that it is not installed. Here is the errror code: Incompatible mods found!...

Solution:
You need a compatible shaderpack from #dh-shader-testing

Iris 1.7.1 crashes on start up

Game crashes on start up with Iris 1.7.1, when I remove Iris everything works fine. Iris 1.7.0 also works fine. I have some mods for QOL features and performance enhancements nothing crazy. I read the crash log and it seems something with carpet mod, but in the end i don't know.

Iris crashes Minecraft when loading any shaderpack on any world

Minecraft 1.21; Iris 1.7.1; Sodium 0.5.9; Windows 10; JRE 21.0.3+9 LTS. My GPU is the AMD Radeon HD 7470, OEM. Crash report indicates an error in atio6axx.dll, which is a driver file; I'm unsure whether the issue is with my driver, or if it's an Iris-dependent issue. I am on the last supported driver update for this card (15.301.1901-160226a-318062E), so if it's the driver then I'm SOL. Any thoughts?...
Solution:
Lovelyโ€”it works perfectly! FPS is radically low, but that can be fixed with some adjustments! For future visitors, here's the link to the mod: https://modrinth.com/mod/forcegl20

Cant download irishaders

Whenever I try to download it (it has been like this for like a year, I have never been able to actually download it) it says I need to pick an app to download it in. It's like it doesn't recognize any java files to download the irishaders onto or something? I have multiple times tried to delete every java and Minecraft file on my pc and reinstall it. I have looked through the hole thing and it still dosn't work. I would really appreciate some help with this issue so I can start downloading. I will put in some screenshots as well....

Iris 1.7.1 for Versions 1.21 and 1.20.5&6 very poor performance

I've been using Iris shaders since 1.20.1 and until/including 1.20.4 I've had great performance (150-160FPS). Since 1.20.5 the performance has been very poor (9-12FPS) and I don't know why. I assumed it had something to do with the devs wanting to wait until 1.21 and then fix the performance or smth (that's why I waited on saying anything), but nothing has changed. The only mods I'm running in both versions are: - Iris - Fabric...
Solution:
I've figured it out! In the video it was enough to set the javaw file to high performance. Since 1.20.5 one has to set the other java file named java in that folder to high performance too....

Game crashing on launch.

game keeps crashing on launch with iris version above 1.16.7
Solution:
This one specifically caused by the mod "Noxesium". Seeing that it's an API mod, it's likely a dependency for other mods. Any other mods in your list that depends on this mod?
