Anti-aliasing problems

[Mozz]

Hi guys,
Just got a new laptop - Sony VAIO PCG K86P
P 4 - 3.2Ghz
1 GB RAM
ATI Radeon 9200 gfx card (guessing its mobility) with 64MB RAM
Still have to post some shots for you guys
but first I need to sort out a little problem. I find that when flying in MSFS, if I press alt or hit "alt + tab" to change music or something, when I come back to the sim, I've lost my anti-aliasing and everything's jagged. If I press alt again (or alt tab) my anti-aliasing comes back (sometimes I have to try a few times). I'm guessing its a driver issue as I'm using the drivers that came with the laptop but if anyone can point me in the right direction:
  Which drivers I should get? (best for the 9200? are there specific ones for the mobility range?)
  And also if anyone knows a precise step-by-step guide to installing the drivers, that's be good. Ive had a lot of bad experiences with the blue screen of death with my old PC and the only thing that saved me was XP
   ;).

Any help much appreciated,
Thanks,
Adam

(EDIT): Also, I forgot to ask. Is it normal for only horizontal parts to be anti-aliased with the vertical sides left jagged.  I know on my Ge force the whole thing was just smoooooth. Thanks again.

It's just one of those things that can happen when switching between screens I believe, I never heard anyone talk about a fix.

I really just wanted to say not to expect too much of that 9200, it's not a very good spec. That's the problem with notebook PC's, they really haven't made any genuine effort at putting decent graphics in them.

Thanks very much for the help congo. Is a shame they haven't put so much time into laptops but this one is working a treat at the moment (I can actually fly the PMDG 737's from the VC  ;D ). Shame about the anti-aliasing but I can live with it (just have to mess around with the settings or press alt less  ;D)
Thanks again,
Adam.

I personally would'nt use FSAA with the video chipset you have, its not really up to it.

I know what you mean. I've tried with and without AA and the difference is amazing. With AA on 3x I can get steady fps locked at 21 (and unlocked it jumps around from 16 to 44). Without AA I can get more than 50 fps. The good thing is it's a widescreen so that the graphics should look ok without AA, it won't matter to much (I hope)  ::).
