Strange continuous glitches in rendering

[Shibi]

a 20 minute video without giving us the timestamp makes it a bit hard, as we don't know exactly the symptom to look for. However, it is a fairly common problem where a lot of old oft-played games will work except a new one that just came out which causes new crashes, blue screens, lockups, or freezes.

If your video card is being pushed, and that can happen with a xx60 level card, then that can cause weird issues on the rest of the PCI bus which can cause slowdowns in hard disk or the rendering itself, plus of course exposes stress-related problems in the hardware itself that might not manifest during your playtime in your more established games, or even in older versions of FFXIV which had the old shaders.

It would make sense to first of all reset your PC to optimised defaults in BIOS, and see if that helps. Removing any OC on the video card, and you can also play around with the system settings and try to reduce the graphics a little to lessen any extra bandwidth the newer shaders are using up over the old.

Checking airflow, cleanliness, and potentially having someone experienced blow your computer out. But in the end, it's likely going to come down to the new shaders adding a stress to your PC or xx60 card that it can't handle. Lowering that stress is a goal in your debugging.
