Thank you for your feedback.

Can you try with the following installer?
//www.sinclairbody.com/downloads/Install-Rob....8-GL4.exe

Let us know if the perfomance improves. This installer contains the 3D engine we will soon use for our official release.
It is a simplified version of RoboDK but 100% OpenGL, it should use the latest OpenGL version available.

Brilliant, happy to help.

I used FRAPS to measure the FPS and few RoboDK example files.

Note: I had to copy the file Qt5PrintSupport.dll from version v3.2.9 to run the v3.2.8-GL4 (I hope that this doesn't make difference for this test)

v3.2.8-GL4: The performance and stability are better compared to the previous OpenGL version. I have to say that v3.2.8-GL4 render the same as v3.2.9. no crash, almost the same average fps across this 2 versions, with one exception: in v3.2.9 the trajectory path lines are not visible (neither the white or the yellow).

• Intel:V-sync: application controlled
  

Best Quaily 36fps (30fps) Best Performance: 36fps (39fps)

• 英伟达方形住宅区V-sync on, Tripple buffering On:
  

Best Quaily: 30fps (39fps) Best Performance: 60fps (60fps)

SprayGun tutorial on v3.2.8-GL4:
Note: if you run the program with the spray gun in a loop, the frame rate drops to 3 FPS after the 3rd time running.

• 英伟达方形住宅区V-sync on, Tripple buffering On:
  

Best Quaily: 3fps Best Performance: 9fps

I found a weird 45 degrees tearing and incomplete frames in any version with the Quadro. But you will find the optimal settings for the current public version (v3.2.9) below with NO weird tearing thanks to V-Sync option turned off:

Conclusions:
If you run RoboDK with Intel HD graphics 520/620 is stable but the FPS would be top 35fps and with more robots and geometries you can expect 20fps or less (traditionally CAD software packages aim for 25-30fps).

My recommended settings

• V-Sync OFF and triple buffering ON.
  
• CPU: Go withHigh frequencyCPU, more than 4 cores is not useful (as with most of the CAD packages)
  
• GPU: go with high computing power. In my tests, 250MB of dedicated video memory were enough.
  
• Complex models?: Maybe a single $800-$1200 nvidia GTX 1070/1080/Titan will get you more performance than a single $3000-$6000 Quadro
