Sorry for a late reply I was caught up playing this UFC game with my brother.
Anyway, yes I am using OpenGL and no I'm not using any of the troubleshooting options on the FSO launcher. Also my drivers are all legit from the manufacturer.
Hrm. You're playing through the main Freespace 2 campaign and you're getting lag when the Psamtik warps in?
For starts, could you make sure you're using 3.6.10 RC3? It can be obtained from the Freespace Source Code Project forum if you don't have it already.
If you mean the .exe the launcher browses to, I'm using fs2_open_3_6_10. I also have one that say fs2_open_3_6_10_RC2 but that one lagged the game even more so I use the other. I didn't know there was an RC3 version. That is probably what's causing the problem. If someone could post a link to the correct one that would be awesome.
Thanks for the help too. I can't believe I never heard of this game before, I was probably too busy playing something else when the game game out. Back in the day one of my favorite games was X-Wing Alliance, and I feel stupid for never playing FS2 until now. It brings back so many fond memories....why the hell don't developers make anymore flight sims for PC!?!? or better yet where the hell did MECHWARRIOR GO!? I want more Madcat dammit!
