For the last view versions (1760 and 1768 I think) I haven't been able to view the mesh without getting error code 3 (560 Ti - timeout) or error code 6 (670 - hardware config doesn't meet minimum specs for the application) messages on my NVidia cards ( 2 different machines - (GTX 670 in one and GTX 560Ti + HD7970 in the other). It might have been occurring longer, but I usually don't open in mesh view.
If I open the file right after I start PS, it goes to mesh view and crashes. If I click on sparse (or dense) mesh button before opening the project file it will stay in pointcloud mode. It would be nice if it defaulted to sparse cloud when you first open a project, since it's faster to load and switch chunks.
My latest project is 49 921 267 faces, 24 975 489 vertices (Isolated to 1 chunk, saved in 0.8.5 format or latest).
