Doom 3, scanlines, and doublescan.

[Ed]

Hi all,

I'm running Doom3 on my Radeon 9700 PRO, at 640x480. I'm using Win2K.
As expected when using such a low resolution, I'm get scanlines (that
horrible TV-like effect) - I'd like to get rid of them. I understand
scanlines can be avoided by using the doublescan feature available in
most modern video cards, but I've read somewhere that this cannot be
done with windows drivers (Linux can though).

Is this true, or there is a way to turn doublescan on in windows? Or
maybe I can remove the scanlines some other way? Maybe the new
Catalysts can help me? I'm using the latest Omega drivers at the
moment, which are based on Cats 4.7 IIRC.

Well, I hope someone can help me. Thanks in advance,

-- Blues.

AFAIK, you should be playing Doom 3 with the 4.9 beta's from ATI, which
might solve all your problems.

why the heck are you playing at 640x480 when you have a 9700 pro??

Agreed - high quality, 800 x 600 here but it also depends on the CPU & RAM

Thanks a lot. I'll try them. Too bad Omega hasn't released any drivers
newer than the 4.7-based ones.

Well, maybe you're right, yes. I'll try it at 800x600. I get ~30 FPS
at that resolution when running timedemo demo1, I'm not sure if that's
OK... BTW, my system is a 2.4GHz P4 with 512mb in two OCZ DRR333
DIMMs. Should I be getting better framerates?

Thanks again.

can you play it without cursing? does it look good? then it's okay to
play. if it's stuttering, then its not good to play. FPS can be very
academic... go with your perception.

again, i don't know about framerates... just tweak the detail settings of
the game to just about max, and then bring them down slowly until the game
becomes comfortably playable.

Well, I set it up at 800x600, medium quality and FSAA X4, it looks
great (obviously) and is very playable, no serious frame drops so I'll
stick at that config. Also, I tweaked my doomconfig.cfg file a little
bit (check http://db.gamefaqs.com/computer/doswin/file/doom_3.txt,
section "editing config-file"), the imageCache worked well for me.

Thanks again.
