I have an AMD 3950 + Nvidia 2060 with 64 GB of ram.
Out of the box I was able to load around 20 characters, then I'd start to see a significant drop in performance.
I spent the better part of a weekend searching for advice and trying A-B comparisons to see what things worked or didn't.
I ended up being able to get ~ 40 clients.
For me the best results where:
#1 - Disable background rendering - 0 fps
#2 - My AMD 3950 ran much better with CPUAffinty=-1 and MQ2CPULoad
#3 - Actor/Clip plane set to minimum
Most of my time boxing 30+ was just grinding XP for guild members and doing some older raids. Sadly we got hit with the suspension waves last year and I'm now just boxing 1 group. Maybe load up 9x TS mules, etc.
PS. I am the author of MQ2CPULoad
. The MQ2 CPU load balancer there was written back when two cores was normal and a 4x core system cost an arm and a leg. Today the CPU schedulers baked into win10 are munch better and the cost of switching cores is a lot less. There is no reason to have it loaded anymore.
