| How to fix an excessive CPU usage by a WINDEV application with HTML or map control ? |
HTML and map control in a WINDEV application is based on the Chromium Embedded Framework (CEF), via the framework's WD300WEB64.DLL module. Starting with version 2025 ‘Update 4’ (304061), high CPU usage may be observed for one or more instances of WD300WEB64.DLL, particularly when the execution environment has limited graphics resources (no GPU, use via RDP remote desktop, TSE, etc.).
Our development team has released an update available in the useful resources :
If processor usage remains too high with the update, add the following value to the registry of the workstation or VM running the application: - Key: HKEY_CURRENT_USER\Software\PC SOFT\wdxxxxweb
- Value: FORCE_LOWEND (DWORD)
- Data: 1
