- The CEF helper process has been renamed from UnrealCEFSubprocess to EpicWebHelper - Support for accelerated rendering from CEF has been added (using GPU->GPU texture copies). This works for the Standalone renderer in DX11/macOS-OpenGL and in the D3D11 RHI renderer, otherwise falls back to the default CPU texture copy mode. Accelerated paint can be disabled by adding "-nocefaccelpaint" to the commandline. - Numerous other bug fixes and perf improvements in the CEF code have been added since we last took a version drop #jira distro-133 #[fyi] wes.fudala #ushell-cherrypick of 15635368 by alfred.reynolds [CL 15651276 by Marc Audy in ue5-main branch]
