Hi, I'm not able to test any other version of the game but GOG ultimate edition (update 1-41028) shows a maximum of 240 FPS during gameplay and a because of my current 144Hz refresh rate, the max FPS value lowers to 144 FPS in menus (even without v-sync). I found ways to change the maximum FPS but since you've already verified an uncapped value in the game's page and because of my limited hardware and refresh rates and a lack of having multiple versions of the game to test, I thought I might discuss this with you on how to implement the changes.
For both DX11 and DX12:
1. Cheat Engine: Searching 240.000000 as a double while 'writable' is set to off and memory scan option is set to Control_DX11.exe or Control_DX12.exe. A singular value will be shown and custom cap can be set (0 will crash the game).
2. Hex edit: Searching 00 00 00 00 00 00 6E 40 (240 FPS) and replace with something else. Examples provided below: 00 00 00 00 00 80 76 40 (360 FPS). 00 00 00 00 00 60 78 40 (390 FPS). 00 00 00 00 00 40 7F 40 (500 FPS). 00 00 00 00 00 40 8F 40 (1000 FPS).
(Note that if the value is set below refresh rate (e.g. 100 FPS@ 144Hz) it will also limit the menu's FPS to 100.)
I'm unable to comment about physics, DXR update rate, particles or cutscene animations' frame rate due to aforementioned reasons; any help in this regard would be appreciated.
