--- Comment #24 from C. Leu kle@bluewin.ch --- Thanks Anastasius Focht for this super detailed answer. Here follows a little addition to that topic.
The only MadOnion / Futuremark benchmark which cannot be directly installed at a 64bit Wine 6.0 prefix is 3DMark99 MAX. The installer crashes shortly after it's started. Maybe this is a different problem. And maybe this installer is 16bit and not 32bit (it really looks old).
My workaround was to extract (with 7zip) the content of the installer (it's effectively a ZIP based self-extractor) into a temporary 3DMark99MAX called directory. After that, the setup can be started properly and the installation finishes also correctly.
However, there is a warning (known problem) that Direct X 6.1 is not installed and therefore the program refuses to start. All mentioned tweaks don't work for me in a 64bit Wine 6.0 prefix. So for the moment the status of that program is garbage. ;-)
Will try this out in a 32bit Wine 6.0 prefix.
