Some problems with RC4 (also applies to latest SVN snapshot)

<< < (2/3) > >>

Bandobras:
Enable MMX in the Makefile (or whatever the win equivalent is).

Anyway, I get around 500 FPS on battlescape and around 100 on menus with a comparable computer as yours (NVIDIA and Linux, though), so there is something bad here...

I compile using Dev-CPP, which uses MiniGW GCC build system. So building is almost just like it proceeds in linux, except that there's no need to use make. Instead, Dev-CPP IDE uses a "Project" concept. So, when I enable AthlonXP as a target and 3dnow as preffered instruction set - it simply adds '-march=athlon-xp -m3dnow' to GCC's command line when compiling. I'll try to compile for i686/MMX, but all the experience I've got tells me that this won't help. Will try to do something with my system (drivers/fresh install/e.t.c), also it'll be worth trying to install linux and check if UFO:AI will work correctly under it.

Got the point, thx. Will try to figure out what is wrong.

I'm having similar problems.  I just installed the Win32 Installer on my system, and the game frequently seems to slow down to the point where it's very choppy; audio and video.  I'm running:
Athlon X2 4800+
2GB RAM
nVidia GeForce 7800GT
WinXP SP2
SoundBlaster X-Fi Platinum

Latest drivers for all components.

This should obviously be more than powerful enough to run the game, so something else is wrong here.  Like LeXa2 reported, if I switched the audio renderer to Dx, the game locked up (couldn't even three-finger-salute out of it, had to hit the reset button).

The game seems to slow down somewhat randomly, but it's very repeatable in the first mission - if I scroll up to where my 8 soldiers are, the game slows way down.  If I scroll away to an unseen part of the map (i.e. the background shows up, but no sprites on screen), it speeds back up.

I also ran into a little bug:  The first mission came up, so I sent my Dropship, loaded with 8 soldiers.  When it was half-way there, I decided to see what would happen if I also sent my interceptor (1 soldier).  Nothing apparently happened.  However, when the dropship arrived and the mission started, only one soldier was on the map - the soldier that was in the interceptor!

I'm not sure if I'm experiencing the same symptoms but occasionally I do get inexplicable slow downs that last 15 to 30 secs or so (this seems to happen once or twice every 30 mins or so). I've only run the game under Linux though. I've found bringing up the console and waiting a few seconds seems to help... I have no idea where the real problem lies. I don't get a slow-down on the first mission moving to where the dropship is though.

This is fixed in the SVN version (which should turn into RC5 soonish hopefully.

Mephisto:
another interesting fact on these "slow-downs":
If you switch to the main menu, everything is fine. After clickíng on "options", it'll start slowing down again (to around 1-2 fps).

Now:

Esc back out and click options again (you may have to do this a few times) and all of a sudden everything is as smooth as it can be.
Now even the mission is playable (just continue)


System:
