OK, didn't know that the Ion is considered to be part of the "GT200 family" (I assume every card named "GT2xx" falls into this category as well) ... you should talk to the marketing department to come up with less confusing naming

Just one question about AccelerateTrapezoids: Is Geforce 8200 considered a member of GT200 family of processors?

I tried: nvidia-settings -a AccelerateTrapezoids=1
and result is:
Code:
  Attribute 'AccelerateTrapezoids' (localhost:0.0) assigned value 1.

I also get the ERROR: Error assigning value 1 to attribute 'AccelerateTrapezoids' (linux-03f3:0.0) as specified in assignment
'AccelerateTrapezoids=1' (Unknown Error) when trying todo nvidia-settings -a AccelerateTrapezoids=1 and I'm running a nvidia gt 240

It looks Nvidia devs are now exploring new features which silently appears on new GPU cores. See VDPAU sets A, B and recent C with divx/vidx accelertation. divx/xvid acceleration did not appeared now just because someone have spare time to code support for it but because new core appeared with improved video engine which now is extended to support MPEG-4 ASP which is core of xvid/divx file format. The same is with trapezoids. Older GPUs are too primitive to support trapezoids well it looks.

As I stated at the very beginning, I have an "older" G92 with a somewhat bigger desktop (3200x1200). I have never bothered with "AcceleratedTrapezoids" and my KDE4 desktop just flies now.

Besides, there was a time, not so long ago, when newer chips were way slower than older ones... Does anybody remember non accelerated sub pixel hinting?

Oh, yes. I definitely remember that. It was the reason that I was forced to stay with Micro$oft Window$ on my laptop until the 180.xx drivers came out. Ever since then, my PC has been single-boot Linux.

Window resizing is still poor, yet XRender is much, much smoother for window resizing. How OpenGL compositing can be so sluggish with window resizing is beyond me.

Disabling the composite extension does improve window resizing a lot.
With composite however I can't feel significant improvements.
