Hi Folks,
I am setting up a machine for LinuxCNC.  It has an Nvidia card installed.  I am running Debian 12 release candidate 4.  My jitter is a little high with the default driver (noveau I think it is called) and so I tried installing the Nvidia driver, but it will not build as it has a dkms file that says `# The NVIDIA driver does not support real-time kernels.` and a regular expression in the file that checks for the string `-rt` in the kernel name.

So, I would like to replace the PCIE card with another.  Can anyone recommend a low profile PCIE video card?

Thanks,
Dan

I had the same problem and switched to an old AMD RADEON HD 7450 1GB DDR3
for 10€. Works with AMD firmware driver. Even with two monitors and no latency issues.
