Nightmare

Maybe combined with XP Pro and those edits on the Guns/Sounds/Aliens anything like that has kind of messed up the original "vanilla" settings? Would it happen if you started up a new game (and didn't save just to see) ?

Hmm. I can try to be of some assistance. It can't get any worse right First off. I think the speed is determined by knots? I may be wrong. But knots are equal across all nations. Whereas kmph and mph are two different things. Knots remain constant. You said when you equip them with plasmaguns. Does that mean if they don't have Plasma Beams that you can still intercept? Or has it just been after you equipped them. If this is so, try a new game but do not save and see if the problem persists. Also if you have a lot of X-COM Game Time and resources see if you equip a ship with 1 Plasma Beam and 1 Avalanche sidearm and see if you can intercept. One other thing I can think of is if your ship had run low on fuel when you had the battlescreen minimised. This means the Interceptor would have disengaged the target while that battlescreen window was still minimised. When you get close and intercept a UFO again (and next time you do) make sure you check the top left of the screen for a tiny little box-window. That is the only other thing I can think of. If both are wrong you may have to start a new game. Chances are if you just got and equipped the Plasma Beam, you can't be THAT far into the game.

Well I tried to sound thing for TFTD. It seemed to DELAY the inevitable. My processor has enough power to run this game and I have basically no other problem now. It seems still sadly my only problem is the sound on TFTD. Which HAS become less frequent; albiet still there.

Ok the sound on TFTD still is crackling a lot. It is annoying Other than that everything seems to be running fine.

Oh ok I'll try it soon ' Thanks a lot guys

Ok so flow has picked up tonnes LOOOOOVING IT! However on TFTD the sound still owns my ears The crackling noise is making it so annoying to play I basically have stopped after 2 USO's downed..

Haha! Oh yeah those Chryssalids annoy me! I got nailed on a Terror Mission where I had 6 after my 5 man team -.- Anywho. Currently I am running. Microsoft Windows XP Pro, Version 2002. Intel® Dual Core CPU. E4600 at 2.40GHz 2 x 2.00GB RAM. DDR1 Nvidia GeForce 9600. 1GB+ Vidya Card Going to try that link that SunFlash produced then if all else fails I will try what Bomb Bloke said Thanks for the help already! Much appreciated!

Hello. I'm new here and saw a few posts and thought you guys were friendly enough to ask for some help. I'm no computer whiz nor am I really bad at them, but I would like some clarification. Not sure if it is of any help; but I am Australian. ?? lol I bought both X-COM: UFO Defence and X-COM: Terror From the Deep off of the Steam Store. I have so far been experiencing some minor problems (which although you can play, it gets rather annoying) Just a quick thank you for reading and your help too Whether you do anything or not; you took time of your day to read this For that I am greatful. First off. UFO: Defence. - How come the Geoscape time warp and the in-game scrolling seems a lot rougher than other times I have seen? (such as YouTube videos) - Why are some Alien movements/death cry noises different to others I have heard? Secondly. Terror From the Deep. - Again. Same problem here. The scrolling and total game movement seems much smoother on other instances I see it. Why is this? - I get a really loud annoying, terrible cracking gargly noise when I save my game. Like someone is popping metal bubblewrap?? lol. It doesn't seem to stop either! I have to usually save the game, abort, re-load the saved game and start over. It isn't hard to deal with but it happeneds easily twice every game if I save at the beginning and around impotant areas ( Such as treading thin lines near an Alien to Stun him lol ) Thank you for any help you guys give I appreciate it
