Hello all, I am also seeing this issue since I upgraded to Parallels 13 when it came out about 2-3 weeks ago. I have been playing around with memory, CPU, video card settings with minimal impact.
- Biggest complaint is the huge LAG in the response of the VM UI / Processing.
- It can take 4-5 seconds between mouse click and screen response at times.
- CPU % utilization does not climb more than 10-15%.
- I am seeing high memory utilization on the Windows 10 VM (60%) System and Compressed memory.
- Performance / LAG is worse in full screen mode with dual monitors.
- Everything was fine with Parallels 12 and Sierra.
My Configuration:
- 2013 MacBook Pro
- 2.7 GHz Intel i7
- 16 GB RAM
- 512 GB SSD
- NVIDIA GeForce GT 1GB
I am considering uninstalling Parallels 13 and re-installing Parallels 12. Please let me know if this is advisable with High Sierra. Let me know what other information you need.
I have also submitted my technical details: 233121873
Thanks,
Russ
