User Interface Lag / FPS Drops with Radeon GPU and 2.0.8
Hello,
I have returned to the game after a very long time away. Really enjoying it. However, I have noticed some heavy FPS drops when there are a large number of menu items / user interface items on display. The main menu is especially bad. Also, the post-level completion summary is bad too. I have a new desktop computer that plays other modern games at 60+ FPS without issue. WFTO is chugging below 30 FPS at the main menu. Main Menu > Single Player menu is possibly the worst. It drops to 16 FPS when mousing over the menu items.
AMD Ryzen 5 5600X 6-Core CPU
32 GB RAM
AMD Radeon RX 6700 XT GPU
Windows 10
Game is installed to an NVMe m.2 SSD. Western Digital Black SN750.
Game version: latest steam release, 2.0.8.
Radeon driver version 21.3.1.
I don't have anything overclocked.
I have my monitor refresh set to 60 Hz. The Radeon software reports my average FPS for my other games at 55-56 FPS. War for the Overworld averages 20.4 FPS.
Additionally, I see a huge FPS drop when activating the Prospector ritual on the Goldrust My Pet Dungeon level. The FPS drop remains until the Prospector map reveal ends. Then the game goes back to 60 FPS.
Disabling Freesync both in the Radeon drivers and in my monitor settings seems like it maybe changing the FPS lag, but I wouldn't call it better. It still lags badly in the Single Player menu and even worse on the Controls menu. It still lags when casting Prospector.
I found that if I open the Controls screen mid-mission and close it with ESC, the FPS lag remains at 10 FPS (!) until I open the Main Menu again with ESC and go into Options.
I re-enabled Freesync and I can reproduce this exact behavior with the Controls menu FPS drop sticking around after closing the menu until the Options menu is opened again. And actually, the FPS sticks at 20 instead of the 10 with Freesync disabled. I'm not sure Freesync is relevant here. The FPS returns to 60 once Display Options is opened again.
