Is the CEF instance for Web Render Top onscreen rendered?

CEF can do onscreen or offscreen rendering. Offscreen rendering is slow because the textures either have to be copied from the graphics card, or everything is rendered via the CPU. Is Touch Designer sharing the actual OpenGL or DirectX textures?

Bonus question: what version of Chromium is being used? How often is the version of CEF used in Touch Designer updated?

The Web Render TOP uses CEF3 off screen rendering, which is hardware accelerated. Textures are accessed via shared memory. Build 099.2018.24410 uses CEF3 version 3282 and chromium version 64 build 1731. The version info can be accessed via an Info DAT pointing at the Web Render TOP. It is updated every few months and probably will get updated in the next month or so, as the current version is from December 2017.
