KDE 4.6.0 and nvidia drivers

There is rather a lot in suse bugzilla about problems with KDE once an nvidia 
driver is installed.  Seems it was regarded as a killer for their release of 
4.6.0 in 11.4.  Ok this is opensuse but from what I have seen bugs just get 
passed on to KDE.

I'm told 32bit crashes but from my brief trials it just went flakey Missed 
clicks mostly.

No mention of problems with 64bit. I would like to know more on this point.

I was running an older nvdia 7600 graphics card and it struggled with the 
desktop effects. The default os nv driver doesn't fully exploit this card.

About time I upgraded the card so fitted a 210 silent. On the nouveau driver 
it's ok but window movement was somewhat jerky to start off with but has settled 
down now. Auto timing changes? - KDE decided to disable effects on the 7600 
within an hour of me using it.

The glxgear performance with the correct nvidia driver for the 210 is about 4x 
faster than with nouveau. Full 1680x1060 res gives 200 frames per sec. Nouveau 
is so slow it's very jerky. On 32bit with the nvidia driver I also saw the slow 
desktop fade in. Currently with the nouveau driver and the 210 that doesn't 
happen but windows do go transparent.

;) I sort of like the effects but to me they mean that os drivers are a no no if 
they are to be enjoyed.

It's nice to see that 4.6.0 is relatively stable so far. Most of my problems can 
be directed at suse particularly on install and ipv6. ;) Mouse miles seem to 
have increased somewhat. I really wonder about where some things turn up in 
relation to the cursor.

On a past post.
Mail now imports perfectly. All I have done is tar'd the old directory and then 
copied onto a usb disc. Previously I just copied the directories across to the 
usb disc. Back to home, untar and import. All works but wish it had imported as 
much as it could in respect to my accounts. This would save a lot of typing. I 
have seen note of early 64bit linux having file problems. I haven't noticed any 
but maybe this was the cause of my initial problem.

Opensuse 11.4 kde 4.6.0
