I don't normally get that queasy feeling from games, but I can say that consistently across all AvP 3D titles, that constant shifting when playing as an alien gets to me a bit too much.

Works fine on Win7 64-bit for me. Have you tried running the game via Galaxy?

Yeah, tried through Galaxy.

It's either the RTX graphics card or (from what I read somewhere) the monitor. Tried switching monitors, but got same thing.

Works fine on a Surface tablet, though, so I'm assuming it's the graphics card.

Just downloaded and played it to test, runs fine on my machine. No issues at all. RTX 2070 and Windows 10.

It's not your card.

Thank you.

I'll keep on checking for solutions.

I do remember getting a headache as a kid to remember which way was up. Then i gave up, and as long as you're holding shift (climb) it didn't matter. :P

Though i never could complete a mission as i kept getting killed by the automated machineguns and couldn't figure out where to go.
