Description

A customer reported that -renderoffscreen leaks when running with an uncapped frame rate

Steps to Reproduce
  • Create an empty project or use the attached reproducer project( see referenced EPS link) and package it as Development or Shipping.
  • Open the task manager or performance monitoring.
  • Run the application with the startparameter "-renderoffscreen", optionally also with "-log" & "-newconsole" for testing.
  • The frame rate should be uncapped per default (t.maxfps 0) so you should already be able to see the shared GPU memory grow. As this is shared memory you'll also see it in an increase in the system memory.

 

Optionally: Run the application without "-renderoffscreen" and compare.
