Updated Sidebar Process.ini to use UsageMonitor plugin instead of deprecated AdvancedCPU which was causing performance issues, making Rainmeter become laggy and borderline unusable. This performance issue only happened when the Sidebar Process.ini skin was loaded.
I discovered that the AdvanceCPU plugin that this skin was originally written with is now deprecated in favor of UsageMonitor, according to Rainmeter documentation:
