However, this doesn't really help, since it's not a regression in that sense.
CSMT is controlled through the registry key HKCU/Software/Wine/Direct3D/csmt, which is a DWORD value. Setting the key to 0 will disable the feature, while setting it to 1 will enable the feature.
Disabling csmt returns the CPU usage to normal levels with wine-3.7. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
