It should allow you to copy the error and send it here Please do so, or I won't be able to help you

That is the error it copies I believe @thinderfg could you send the full log? If you can recreate the failed shader load again it will be in latest.log

whre would the log be? it said to copy this shadowcomp compute shadowcomp1_a!

Logs folder

Nice. It's called latest.log, and it only contains the error if you didn't restart the game since you got it

wow that's sad (the driver doesn't support compute, but failed to say so in the OpenGL list)

You should try updating your gpu driver, your GPU is supposed to support up to OpenGL 4.6, which includes compute shaders. I am intrigued by the fact that shadowcomp1_a triggers the error, as there are multiple compute shaders in shadowcomp before it

I don’t know I can check when I get back home

You're getting a shader not supported by hardware error.

Oh

So it either bad drivers, need to update drivers, or you use a very outdated GPU. Perhaps even the forcegl20 mod might help you.
thinderfg
thinderfg2w ago
Okay should I check my gpu?
ITL Supress
ITL Supress2w ago
Radeon Vega 3 iGPU. Thats what you got.
thinderfg
thinderfg2w ago
Is that good?
ITL Supress
ITL Supress2w ago
Its built into your processor so no.
thinderfg
thinderfg2w ago
Ooh
ITL Supress
ITL Supress2w ago
Its also one of their lower end skus. In that catagory.
thinderfg
thinderfg2w ago
Ooh
ITL Supress
ITL Supress2w ago
But it should have the correct support to run the game.
thinderfg
thinderfg2w ago
I can run Minecraft fine

That won't apply here. Since its clearly a feature a mod added thats not supported maybe the shader itself. https://discord.com/channels/774352792659820594/1249826578112970753/1253043083327574117 You can try ForceGL20. For your mc version. It might work.

I am also using Minecraft 1.21 Okay but it is a shader problem not iris problem?

https://drivers.amd.com/drivers/whql-amd-software-adrenalin-edition-24.3.1-win10-win11-mar20-vega-polaris.exe This is the newest AMD Driver you can try that as well. Seems to be hardware or shader based on log. Using ForceGL20 and new drivers isolates for hardware. If it still happens after that it has to be an iris thing with AMD iGPUs.

How would I do new drivers
Piotr Barcz YT
you find them and install them
thinderfg
thinderfg2w ago
Where would I download new ones
Piotr Barcz YT
you'd have to google that
thinderfg

Okay

Guess I'll take a dip into this issue page. :facepalm: Classic case of outdated GPU driver.
