GeForce says I can run FleX gib settings optimally, game won't let me use FleX at all

[Wallaby]

The software panel that came with my NVidia graphics card will arrange my settings within games to run at their optimal settings, however I still cannot use the FleX features in Killing Floor 2 as they are locked, which is very frustrating because I was allowed to run Gibs AND Fluids during Early Access and I never suffered any crashes as a result.

Help / advice please

## Edit: Setting mysteriously unlocked, which is odd because I had restarted my computer before when I first discovered this issue and still I was locked out and there hasn't been any update since then to my knowledge, so I don't know. If you had also experienced this issue I'd like to know if I hadn't been alone.

In nvidia control panel > physx there should be an option to use your gpu for physics (because i think by default it set to use cpu which is not good)

Also not recommending using flex at this time as it severly reduces performance.

Also important question: what graphics card are you running?
