RTX Remix

Path Tracing in Old Games with RTX Remix graphics and performance comparison in 7 Games at 4K DLSS 3.8.10 Quality/Performance + DLSS Ray Reconstruction with Path Tracing and Ultra settings on RTX 4080.


0:00 - GTA San Andreas
1:54 - Need For Speed Underground 2
3:47 - Need For Speed Underground 1
5:41 - Need For Speed Most Wanted
7:33 - Max Payne
9:28 - Portal 2
12:00 - Half-Life Path Tracing Mod (bonus comparison, not actual RTX Remix project)

 
Some are better than others, but Portal 2 looks moody AF and I want to try it.

But holy hell, those framerates! Every single game was sub-60FPS, and quite a few were below 30FPS, and all report playing on an RTX 4080 at ~2800MHz... Yikes!
 
What's actually going on with the geometry / lighting glitches in all those "remixed" titles? It appears to be happening pretty consistently in all of them, that you have either notable flickering in the diffuse channel at some spots about once per second or some wrong vertices that somehow get offset by several pixels. Some of them even periodically, as long as the scene doesn't change.

Artifact from failed ray reconstruction? Or some other post-processing issue? Or is there some cyclic garbage collector reaping the luminosity cache and somehow that results in garbage being used to fill in for the wiped values?

EDIT: No wrong vertices, just reflections in puddles from that that weird animated water shader they all share and even use for puddles... But the flickering in illumination is there.
