Open Stage Control - performance test against vsync
Raw
test.md

Abstract

Disabling chromium vsync seems to have a big positive impact on perceived perfomances (aka input lag) in Open Stage Control.

I'd like to verify that.

Requirement

Having chromium v49+ installed

Test procedure

A

  1. run chromium without any command-line switch
  2. browse to http://demo.osc.ammd.net/
  3. open the first session, drag the faders up and down

B

  1. run chromium with the following command in a terminal : chromium --disable-gpu-vsync
  2. repeat 2. and 3.

Desired feedback

Is there a noticeable performance difference between tests A and B ? In which case the faders are the most reactive ?
