Since updating to 5.1 and reinstalling FS2Crew I get stutters and flashes when FO runs checklists in VR in the NGXu. I have Cosmos HMD and nvidia 2080 TI with I9 and 64 ram, overclocked to 4.9.

 I tried lowering resolution and texture quality but no help. Any suggestions on possible tweak?

Resolved.  Turning off the green speech bars solved the problem..no more flashes.

Thanks for sharing that solution..  must be a VR and 5.1 conflict.
