Description

With kitxr 107.3.111, we can save cpu time by skipping writes to usd stage since all the data is in fabric. This gives us back 11ms (on my machine) on the main thread. Additionally, texture streaming was bottlenecking the render thread. Disabling gave us back 11ms on the renderthread. Together, it gave me back 11ms.

With kitxr 107.3.111, we can save cpu time by skipping writes to usd stage since all the data is in fabric. On the tested workstation, it saved 11ms on the main thread. Additionally, texture streaming was bottlenecking the render thread. Disabling resulted in 11ms savings on the renderthread. Together, it resulted in 11ms on the tested workstation as those two bottlenecked each other.
