skelleher Posted March 22, 2019 Posted March 22, 2019 Hardware: MSI gs65 Stealth notebook with RTX 2070 Max-Q OS: Windows 10 Drivers: updated as of 3/22/2019 The Vive Pro is not detected as an external display. I have tried two different miniDP cables (from Cable Matters; both cables were recommended on this forum). They are DP 1.2 / 4K / 60Hz compatible. Another external monitor is properly detected, so I know the miniDP port is working. I've been driving the Vive Pro with a GTX 970 so the RTX 2070 Max-Q ought to be fine; are their known issues with this GPU? RTX 2070 is on the supported list, but the Max-Q is not.
skelleher Posted March 22, 2019 Author Posted March 22, 2019 Some progress: I re-ran room setup, and could then see the home room on my HMD. However the right-hand side was glitching badly - random, brightly colored polygons everywhere. Power-cycling the HMD / linkbox and restarting SteamVR made that go away. Now I can see the home room but there is very bad judder when I move my head. SteamVR settings page shows 17ms render time and "motion smoothing on" whenever I move. When my head is not moving I see 3 - 7ms and "motion smoothing off." Will update this thread as I progress, but so far this RTX 2070 laptop has not been a good out of the box experience.
skelleher Posted March 22, 2019 Author Posted March 22, 2019 The MSI Dragon Center showed my GPU severely under-throttled: core clock of ~800 MHZ and memory clock of ~800 MHz. I plugged in the power supply and GPU jumped to 1500 MHz core / 6200 MHz RAM. The GPU is at 60% load 76 degrees, and the fan is SCREAMING. There was much less judder, but the home room still skipped frames as I rotated my head. After just sitting there for five minutes, the skipped frames stopped happening. Frame time is a pretty consistent 9ms now. /shrug/ Fan noise is very serious. I didn't expect this for a $2700 laptop while in the home room. Buyer beware.
