Need help: Low FPS after five minutes of play

[Shafir]

Here is a comparison (1.52). Fullscreen. Fresh loaded savegame. RT Ultra (without local light source), DLSS Balanced.

WQHD, Ryzen 3700X, MSI 3070 8GB, Geforce 512.15, DLSS 2.3.9, 32GB RAM, WIN 10 Pro 21H1

1. Texture Quality Medium - 54 FPS - everything o.k.

...but just moving a few steps further, this happens:

2. Texture Quality Medium - about 20% FPS loss and peaks in frametimes - problems with transparency?

3. Fresh reloaded scene, but with Texture Quality high - FPS back to 50+

4. Texture Quality high - FPS halfed to 28, VRAM at the limit.


It's kinda...weird. This happens in scenes with heavy lightning situations.
