6/15/2023 0 Comments Fusion pro 12![]() I had the same issue when upgrading to Big Sur and Fusion for all your effort on finding a reproducible case to for the deep analysis and workaround. I do appreciate all your help and assistance in identifying and diagnosing this issue. ![]() Rest assured we'll include these particular operations on our test scripts/suites going forward. We are all well aware CAD applications are important to our users, and we do regularly test several of them, but we weren't exercising the UI operations where these performance regressions were most apparent. I can only apologise for not catching this before. Krisk09, I hope this will also address Crestron Simpl and Crestron VTPro performance regressions too. This will disable GDI HW acceleration, and have no other consequence (for example, Direct3D 11 should still work.) In the meanwhile, these performance regressions can be worked around by adding =FALSE setting to the. We're still investigating why these applications are so adversely affected, and how to properly address it. ![]() We now know this issue is related to GDI hardware acceleration, a feature we recently implemented and that in theory should accelerate ordinary GDI windows applications and save battery by moving the workload away from the CPU to the GPU, but on this case it appears to cause the drawing to ping-pong between the CPU and the GPU, effectively having the worse of both worlds. ![]() We were able to reproduce this issue in-house, thanks to LowcountryLDC's video and Autodesk Civil 3D template. ![]()
