You can see it if you middle click on any TOP. Also Windows 10's task manager has GPU reporting tools as well.

Hi Malcolm,

OK that what I had in mind, I didn’t miss anything then, will do that for now, best, P

Hi Malcolm,

So here is a sum up view:
A - The more i reduce the number of points to show with my shader (it takes points from a few TOPs in .exr formats and displays them in 3D, position and color are store in the .exrs), the more fps I get, with 16million I am OK. In editor mode TD says 90fps.
I attached pics
B - The GPU of the card isnt that full (less than half) see pic of Win10 Task Manager, also see GPU 3D at 98%
C - The openVR TOPs it seems are taking all the resources see pic of Perf Monitor
So it's weird, I am thinking my shader might need a faster card? It renders all points if I let it but very slowly, the ram isnt full but as i said more points make it slower.
OR I need to update / check my VIVE Open VR network.
Maybe the card needs bigger internal "buses", or RAM transfer speeds? No idea, that's why I wonder which:
Quadro or Titan?
Best!, P

GPU at 98% means the GPU itself is overworked. It's not a RAM or transfer speed issue. So you need something with more cores/faster cores

Thanks Malcolm,

Let me ask this then: how is it that TD is going to offload more calculations to the CPU?
Is it automatic somehow? Does this mean that a bigger GPU is not going to help? It's just that the less points I display the better my framerate goes, and that is pretty linearly verifiable, best! P

Hey you know what I thought you mentioned the CPU, so OK, I need a bigger GPU.
Fine, is the Titan V versus a Quadro P5000 a good choice then?
Best! P

If I can get my hands on one :), or a previous Titan, P
