After updating from version 1.21.114 to 1.21.120 the RAM gets flooded from the application - before the update just a view GBs but no it seems it just uses every single bit of RAM and doesn`t release unused.

Do you have the Improved Input Response option enabled in Settings > Video? If so, does the issue still occur if you disable it and restart the game?

Note that the option cannot be adjusted if Vibrant Visuals is enabled, so make sure to disable that first if it's enabled.

Thank you! That seems to do the trick. Out of curiosity - this option was activated all the time without causing any issues - why now?

Best regards
