Okay, I replaced the drivers with new ones that AMD didn't want to admit existed and it worked. After two months I can play again! Gentlemen, thanks for your help and patience with this less-than-savvy player.

Kveller: Yes, A Radeon accelerator, which is an AMD product. I'll look into that. Dark Pulse: Downloaded 3.7.2 and installed it into a new directory. Everything works except soldiers are still invisible. guess it's the AMD issue.

They were probably from a very old incarnation of the game that I've had sitting around for years. I tried resetting to default state from inside the game through the Options feature with no success. I copied DOOMII and the gzdoom items over to a new directory and sure enough, there is the gzdoom-user.ini file. That's what you're talking about, isn't it? (I've included a screenshot) How do I go about wiping the config files like you mentioned? I assume you were referring to gzdoom-user.ini?

Thanks for the reply. I'm not sure how to do that. I have 2 - default.cfg and modem.cfg. Do I go into them with a text editor and delete the contents, or just delete the cfg files hoping that they will be remade? Or can I just go to "Options" and click Reset to Default"?

All monsters have become invisible. This began a few weeks after I switched to a new machine using Win10. At first I thought I had accidentally toggled something in the options but haven't been able to find anything there. I was using gzdoom v3.5.1 and zdl.exe (can't find version # for this) to launch. I've tried d/ling new versions of both in case they were corrupted. Next I tried changing compatibility settings back to Win7 in properties. I even went back to the old method of running the game from a dos batch file but still have invisible monsters. They operate properly - still kill me quite nicely but they don't show. Does anyone have ideas what's happening?
