Another data point.
I'm running Intel i7-9700F 3.0 GHz base, 1660Ti, and 32 GB Ram at 2666MHz. I've been toying with settings from VR4DCS, Mastiff, Lukas, and no matter what SP is steady 40 fps at best (because I fixed it in ASW, didn't like the stuttering from 80 fps to 40 when banking or flying low) but MP is nearly always 20 on busy servers. CPU doesn't look bottlenecked, RAM use 18-20 GB in busy servers so I'm wondering if everyone else is just dealing with 20 fps in busy MP as unavoidable fact in 2.5.6 open beta.
I just upped from 16 to 32 GB RAM and the main difference is now I can actually join servers with greater than 10 people connected.
All DCS options near min, PD 1.4 set by Oculus debug tool, latest video drivers. Thinking to roll back to 2.5.5 to check but then I lose most of the good MP servers so kind of defeats my goal to increase frames in MP...
Is anyone getting 40+ in Hoggit servers for example?
