In every game that support 3.1 there is an issue with using Frame Gen on both AMD and Nvidia GPUs. The fix for AMD seems to be tuning Anti Lag off, however there is no way to fix this with Nvidia cards. The turning off Reflex, the Nvidia equivalent of Anti Lag doesn't work.
Is the team aware of this? Is there going to be another update to these games?
