Summary 0027879: Draw Harness, ViewerTest - disable VSync within non-interactive mode
Revision 2016-09-17 13:33 by kgv
Description OpenGL context enables vertical synchronization (VSync) by default since #0025556.
This option is intended to eliminate visual artifacts on the screen within interactive mode, however within non-interactive mode this option makes no sense.

At least on Windows 7 platform, VSync still affects performance in non-interactive mode, when window is not displayed on the screen at all.
This increases time required to perform tests on hardware with fast GPU and potentially affects CPU usage statistics as well.

It is proposed to disable VSync in non-interactive mode.
