When zoomed into my model, I am noticing significant lag when panning, rotating, and trying to sketch. I did not see this issue previously when using 11. I updated to 12 due to an update of my graphics card but I am still editing a file created in 11.
I haven't used Creo in a while, but I don't remember it being like this.
The image shows how far away my sketch cursor is from my mouse. After a bit the sketch cursor catches up. Is this behavior normal?
I was able to figure out a workaround/fix. The issue is caused by some sort of issue with Creo's opengl with my graphics card. It is not clear to me why there is an issue as all my testing indicates that my graphics card and drivers can run the latest opengl version.
To overcome this, I set these values in the configuration file:
graphics opengl
use_software_opengl no
ENABLE_OPENGL_DEBUGGING yes
ENABLE_OPENGL_FBO yes
ENABLE_OPENGL_SHADER no
ENABLE_OPENGL_VBO yes
The most critical of these being ENABLE_OPENGL_SHADER set to no. The description of this is: "Enable advanced OpenGL capabilities including HDR lighting, Ambient Occlusion and Order Independent Transparency". In the 3D workspace, disabling this reduces the quality of graphics, but at least the lag is gone, which I think is better than nothing,
