Thank you for replying. As soon as I get a chance, I'll check the resolution and try Full HD if applicable. The demo time limit makes experimenting with settings a bit difficult, since I often have to restart the program. I'm sure Vsync and shadows were disabled.
Here is my log file. Sorry, If I'd been thinking, I would have attached it to my question.
Thanks for the link to command line options. There is one intriguing option:
--no_threaded_ogl Disable the use of OpenGL via multiple threads.
I don't know if that really means disabling Threaded Optimization, but it's worth trying. I'll let you know what happens.
I really appreciate your help.
