I debated a lot where to post this, but since it technically applies to all(?) W3D engine games, figured here was best?
I doubt there's any issue with this, but just to be safe ill not post the exact method, so if i get in any trouble ill be the only one to blame
as the title implies, i got IA (and other games) running on Vulkan, and then via Vulkan applied frame generation.
being as its a hack on a hack its not flawless, but works pretty well, also since game is locked to maximum FPS most of the time anyway, fairly pointless.
but under load from 160 bots and with vis disabled, was able to get -about- 60 real fps, and 120 with generated frames i made a video:
(i am apparently far to stupid to properly embed video? so heres the link instead)
Link to IA Vulkan Frame Generation MP4 (compressed + downscaled to 1080p) (Akaris is me, "Dayofnuke" is actually very old name)
you can spot some of the generated frames as bots load in causing a fps dip, but otherwise fairly smooth after that, so this method maybe helpful for PvE sometimes
using a very similar method, DX12 should probably be possible? and between Vulkan/DX12 applying Ray Tracing is also theoretically possible, but that would be ~much~ more work than FG
