I use x11/nvidia-driver and never had an issue (even on low to mid-range cards) with this when properly configured (the documentation currently has a reported bug that leads to a misconfiguration [you need to load nvidia.ko as well as nvidia-modeset.ko in loader.conf and not post device probing.... if you load it in /etc/rc no acceleration for some reason]). Also it is app dependant like anything that uses libxvid or the equiv works fine (including stuff that turns it on in opengl) for example xine works without issue for me (I am not picky though as long the frame rate is high enough to fool the eye, it plays back in real time, you can see all the details of the original frame if you pause it and words and lips are in sync I really don't care about much else [degraded resolution is ok, dropped frames are ok, etc.]) > > On Tue, 23 Jul 2019 11:27:03 +0000 (UTC), Paul Pathiakis wrote: > >However, even when you settle on graphics and storage media, check the > >power consumption.

Since there is only a $15 (at most) between 450/600 W (roughly the same price range) and 850 W I mightiest well do overkill (who knows what I will be attaching to the machine in the future due to the nature of my work [for example last year I had a EKG monitor attached to it for development purposes, earlier this year I had a computer controlled turnstile [used a subway fare gate] attached to it for professional reasons). PSU's are one thing if I have any option I want overkill... in other areas like keyboards and mice I want el cheapo ones (I am very rough on them some how and even the most expensive and "high use" ones last no more then 6 months to a year so it is cheaper to just buy $10 ones every 3 or 4 months)
