Graphics card is not using full clockspeed
« on: October 01, 2016, 10:31:45 AM »
Hello,
I noticed that the memory of my graphics card (ASUS GTX 970 Mini) is clocking at 3004 Mhz instead of 3506 Mhz while building the dense point cloud. I think I lose some performence here, how can I fix that problem?

I fixed the problem using NVIDIA Inspector 1.9.7.7.
With this software I was able to increas the clockspeed of the memory from 3004 MHz to 3704 MHz. I changed these values at: "Overclocking" --> "Performence Level [2] - (P2)" --> "Unlock Max" --> "Memory Clock" -> 3704 MHz

I used the "monument" data sample from Agisoft to test the improvement in performence for the dense point cloud construction. Here are the results:
Before: 873,70 Mill samples/sec
After: 999,28 Mill samples/sec
+14% faster!
