Thanks for the advice, I’m happy to try anything to improve multi screen performance.
Can you tell me what “secondary scaling” does or changes? Does it set the second and third monitors to scale to 70% or 80% of the resolution of the main display?
Would that be any different to me setting the second and third displays to a lower resolution, like 1440p? I havn’t noticed much of a performance difference when doing that - its the main thread that is being killed by multi monitor, not the GPU
