This is a follow-up to thread 98817, where the "Use Compatible OpenGL Profile" option was added in v2757 to address OpenGL not being detected under Parallels. As of the versions below it is still not detected, but the environment has changed in a way that may be useful for diagnosis. Parallels Desktop 27 ships a new Windows 11 ARM display driver with OpenGL 4.3 support (https://kb.parallels.com/en/115487). This is the same OpenGL version that VMware Fusion exposes, and Sierra Chart detects OpenGL correctly under Fusion. So the version-number theory from the original thread no longer explains the difference between the two. Configuration: - Sierra Chart version: 2939, ARM64 build - Parallels Desktop 27.0.1 - Windows 11 ARM build 26200.9168 - macOS Tahoe 26.4, Macbook Pro M5 Max (40 core) Behavior: With both "Use OpenGL for Chart Graphics" and "Use Compatible OpenGL Profile" checked, after restart only neither remains checked. OpenGL Extensions Viewer report showing OpenGL 4.3 / GLSL 4.30 Request: Would it be possible to add a Message Log entry stating the specific reason OpenGL initialization fails (pixel format selection, context creation, missing extension, version string parse, etc.)? That would make it possible to narrow down what differs between the Fusion and Parallels drivers without guesswork on either side. |
