For the directory variables, if you're using the Flatpak version of Steam you'll want to change lines 8-10.

With CaptureAge 1.10.0 I face the following error after setup via Proton 8.0-5:

ERR: ProgramExecutableD3D.cpp:1351 (getVertexExecutableForCachedInputLayout): Error compiling dynamic vertex executabl
e:
C:\fakepath:5:1: E5000: syntax error, unexpected NEW_IDENTIFIER

After upgrading to Proton 9.0 (Beta), there is no longer a terminal output from Capture Age (regression?) but PROTON_LOG=1 reveals the following:

vkd3d:07ac:fixme:hlsl_yylex Unsupported preprocessor #pragma directive at line 6.
vkd3d:07ac:fixme:hlsl_yylex Unsupported preprocessor #pragma directive at line 6.
vkd3d:07ac:fixme:hlsl_yylex Unsupported preprocessor #pragma directive at line 6.
vkd3d:07ac:fixme:hlsl_yylex Unsupported preprocessor #pragma directive at line 6.

#pragma is found in the DLLs d3dcompiler_47.dll and libGLESv2.dll. Renaming/moving/deleting both made CaptureAge start up successfully.

EDIT: If CA is started first, it can make AoE 2 DE to load the record, but then somehow fails with the error "Age 2 connection lost" and tries to start the game (again, which fails).
Doing the opposite - CA button in the AoE 2 DE replay mode - results in the popup "Failed to open CaptureAge to spectate the current game." Wonderful.

@SmallJoker Cool. But I imagine the two apps still cannot communicate?

@luisvalenzuelar Interestingly, CA does find the game process and can in fact tell it to load and play back the record. That's as far as I could get because connection is afterwards lost for no obvious reason. My CA is currently not in a usable state beyond having access to its main screen and a list of saved games.
