Windows 10 will reach end of support on October 14, 2025. The current version, 22H2, will be the final version of Windows 10, and all editions will remain in support with monthly security update releases through that date. Existing LTSC releases will continue to receive updates beyond that date based on their specific lifecycles.
I wonder if it would make sense to sell 4090 and buy cheaper amd card before Linux switch. Problem is I from time to time play VR and also do blender sometimes so probably canā€™t. Does nv optix work in Linux ver of blender?
I don't know how good it is, but for Turing and later GPUs there's a new official open source driver being developed. You'd likely have to use a more bleeding edge distro to get that.
VR works depending on your headset. Index is fine, Oculus doesn't work.
You could make a usb stick of your desired distro and test everything without permanent changes before commiting.
