When CT is slow in Windows without any specific reason

If an application executable is set to compatibility mode, it may operate up to 5 times slower without any apparent reason. Since Windows can automatically enable compatibility mode even if the user does not configure it manually, it is recommended to check this setting if CT 2024.12 performance is slow. When compatibility mode is enabled, performance degradation may occur due to the following reasons:

Causes

Optimization Failure

• Slowness when the Windows Compatibility Layer (Shim) intercepts API calls in the middle.
• Redirecting a newer API call to an older API causes extra computation and slowness.
• Performance degradation due to using older Windows APIs.

Additional security checks.

• Additional authorization checks due to modified security policies when applying compatibility mode
• Overhead due to unnecessary security validation procedures

Solutions

1. Right-click on the CT executable file and select [Properties].
   
2. Go to the [Compatibility tab] and find the compatibility mode setting.
   
3. Uncheck compatibility mode
