Symptoms

Poor GPU power utilization across all graphical settings. Frame rates are almost always below the target 60fps (20-50 usually).

The GPU is running at 95-100% utilization but at low power levels. GPU power is always ranging between 130-180 / 220 W.

The CPU utilization is low (no cores are at 100%), and also the GPU memory is not full (usually 1 or 0.5 GB of free vram remaining). I see no obvious signs of CPU or GPU bottle necking.

I played the first 15 minutes, and the issue was constantly present. No combinations of graphical settings appeared to help. Using more intense DLSS3 settings (Performance & Ultra performance) slightly increased the frame rate, but did not solve the issue.

Using different Proton version, including GE-9-21 did not help.

Reproduction

The issue is always present. No steps required to reproduce.

Just want to confirm that a few months after launch I still have the same issue with a 4070 Ti (tried both the 560.35 driver & the 565.77 driver), the most recent 6.11 kernel on Ubuntu 24.10 on an i5 12500 with 32 GB Ram. Earlier sections of the game with smaller maps run great but many larger areas (Lostwing/Northreach) are dropping down to 30 fps or even below with extremely inconsistent frame times and/or stuttering in some areas, which reportedly does not really happen on Windows. CPU and GPU usage has a lot of headroom. No other demanding games (e.g. Silent Hill 2, Cyberpunk 2077, Indiana Jones, Dead Space Remake) run this badly on my machine. Recent Proton updates that claimed to improve the performance in FFXVI did not help.

Might be a general problem of Nvidia driver + VKD3D, or it might have something to do with DirectStorage emulation, because apparently FFXVI uses this a lot. Would be great if someone more knowledgeable about Proton/VKD3D with an Nvidia card could take a look.
