Hi Andy
Any chance of seeing the "what's new" release notes before deciding, as I'd rather not overwrite my existing V8.55 just yet.

Hi Andy,
Do not know if it is a AMD Radeon software problem or AC3D but with the latest version of AMD drivers 21.2.1 AC3D will not run, opens start-up DOS window then nothing. Reverted back to version 20.11.2 and all is okay.
Windows 10, Graphics card is a AMD Radeon R9 200 and AC3D version 8.6
Tom.

This has not been reported and many are using the latest AC3D. It think it's unlikely due to the AMD but it is of course possible.



There is a known problem with the preferences/settings file. If you ran 8.6 and then went back to 8.5, it won't start up properly. A solution is to delete the ac3dprefs8.txt file from you home folder. Could it be this?


If not, please could you try running it from the command line with "ac3d -debug"?

Hi Andy, AC3D working no problem with drivers 20.11.2, updated to latest drivers 21.2.1 and AC3D stops at dos window. Run -debug and came up with a lot of lines in dos window but still no AC3D. Is the debug information stored anywhere? Change back to drivers 20.11.2 and AC3D working fine. For now I will stay with the old driver untild the next one comes out and try that, Tom.

[Andy]

Thanks Tom, it looks like you have confirmed the problem.



To save the debug info run AC3D with "ac3d -debug > output.txt" and that will put the info into the output.txt file.

Get access denied when I use "> output.txt", "- debug" on it's own works

The file needs to be writable.

ac3d -debug > c:\users\tom2\ac3d.txt

should do it.


I suspect you won't see a problem - it's probable that AC3D simply failed to open the OpenGL window because of the driver problem.
