It is... only from what i can see it doesnt provide any differing information. Ill need to wait until someone else can identify this.

From what we can tell, you are using a shader that is unsupported by Iris at this current moment in time

I am using BSL v8, which is clearly stated as supported in the the Iris page

Please try updating your gpu driver to the latest avaliable, you have 340.108, latest should be 442.19

commented

well, i tried that, but for some reason that driver doesnt even use the GPU

commented

The game doesnt use the gpu after you install the latest driver?

commented

The OS doesn't detect the GPU

This seems like a recent nvidia OpenGL quirk, according to https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/187711/error-c5121-multiple-bindings-to-output-semantic-c/. Changing the used GPU could definitely change the output in this case.

If you've a Nvidia card, open the Nvidia Control Panel, manage 3D settings, and ensure 'High performance NVIDIA processor' is selected as shown. Not that that'll fix the crashing issues, though.

umm....that is for windows, i use Linux

commented

I tested with the new driver and it worked perfectly

commented

Then this was likely due to a mismatched driver.
