I have a big and expensive GPU 3080. My experience with Ubuntu 20 was fine.
Right now with ubuntu 22, the performance of the GPU connected via display port is worse than what I get on some embedded graphics card on t16 lenovo laptop, which is unacceptable.
I’ve tried multiple things, like updating to latest mesa drivers, going to kernel v6.2, having all my libraries as upgraded as possible, but the issue still persists.
Please fix this, it’s crazy that official drivers from NVIDIA offer worse performance than embedded graphics on a laptop…
