Fullscreen Hanging or Locking PC

[patrjck]

Hello, I just installed OpenXcom. The game is running great and looks fantastic, but I'm unable to play in fullscreen.

Resolutions tried:
800x600
1024x768
1280x720


Whenever the game goes to fullscreen the screen goes blank and the computer stops responding to commands. I've waited up to 30 minutes but the computer never responds, including uses of Ctrl-Alt-Delete, and I must eventually shut off the computer. During the hang, drive activity continues periodically, but the menu music only plays until the end of the "song" and never restarts. I'm unsure if this issue is a bug or user error. I've also tested this with the latest nightly and the same issue occurs.

Is there a solution?

Update: If I sandbox the game, then I'm able to play fullscreen without any issues whatsoever. No delay or lag has been observed, so I'm unsure why it works this way. Regardless, I have no reluctance running it this way as long as saves persist.

What filter u currently used? If u used Open GL and the graphic didnt appear then ur pc might not support that. Did u ever tried it without filter?

I was using "-" when I first ran it, but now that I'm running it in a sandbox I've tried them all and they work great, except for SABR which slowed my system to a crawl until I took the resolution down a few notches. X-Com has never looked better!

My personal favorite, and the one I'm currently using, is Quilez.

So the problem is in the geoscape screen. I suggest patch ur copy of original X-COM DOS version or use the pc complete edition.

So did u have no problem played in windowed screen?
