Here's a list of QoL changes I'd like to see implemented.
Sensitivity Scaling Changes
Currently the sensitivity scaling is somewhat wack, even at 400 dpi the higher ends of the sensitivity bar will never be useable and for high dpi players it's impossible to use low sens. It's also unnecessarily difficult to match your sens from any other game or to have a 1:1 ADS and hipfire sens. It would be very helpful if the overall scaling was reduced by a LOT and ADS/Ship was changed to a multiplier of your base setting instead of it's own value. Currently via hex code editing (using this site's converter https://www.mouse-sensitivity.com/) the lowest sens possible in the settings file on 1600 dpi is still in the range of medium, with low sens being impossible.
Frame Caps
It's 2024 and it's very common for players to own 165, 240 or even 360hz monitors now, however the game only allows for a max frame rate of 144hz. This prevents players from syncing their frames to the refresh rate and adding input delay. Through experience with unreal and independant testing in marauders itself I know the game is capable of rendering far beyond 144hz while being stable. The 144hz limit is an arbitrary value imposed by the game UI, not a limit of the engine or the settings file format. Removing the preset options and making the framerate limit a custom value would be a very easy and helpful change.
Black Screen/Tinnitus Accessibility Changes
Flash bombs can be quite jarring to some players with light sensitivity issues, tinnitus or both. Adding an option for a flashbang black screen rather than white and an alternative flashbang sound would be extremely helpful.
