Before anyone says anything I know that I have posted about this problem before and I have asked on #planeshift and I have searched the forum

Am currently using Platyna\'s last release have reinstalled it 5 times in the last week or so have also tried xordan\'s new installer but that Segfaults just before entering the game
System
Asus A7V8X
AMD 2500
1GB Ram + 1GB SWAP
250GB sata WD Caviar
MSI/Nvidia FX5600 ultra
**2mb ADSL
SuSe Linux 9.3pro KDE
latest nvidia 7676 driver (updated to try and cure this problem)
Full description from start
problems started about a fortnight ago but thought it was network lag, then at the end of last week the client started locking momentarily 5-10 seconds at a time, this has gradually got worse and worse until now I can get maybe 10 minutes to move/chat every half hour and it now affect any other progs running (Chat,firefox etc)
While locked top shows continually changing CPU/MEM %\'s from 30-50%cpu and up to 90%mem and one or the other of the following messages scroll rapidly through the terminal, KDE\'s system guard show maxed out CPU/ram plus half the swap!
*** Input Buffer Full! Dropping packet of type 13! (and types 115, 49 and 28 but mostly 13)
Got DR message for unknown entity (various numbers I\'m at work and can\'t remember exact numbers)
Sorry for the long post but if anyone could point me in the right direction I\'ll give you a mushroom in game

regards
John, Hokinon, Lanser or whatever

Some things that I have tried
updated graphics driver
-nolightmapping
Full screen/windowed (different sizes)
a lighter window manager (Fluxbox,enlightenment and WindowMaker)
sound on and off
Crying, Shouting, Swearing, general ranting \'n\' raveing, kicked the cat and the dog (twice), drunk loads of beer (but just fell over), tried to kick the other dog but couldn\'t catch her and am now counting my pennies to see if an upgrade is affordable.
**@Seytra Thanks for the suggestion Have just run glxgears and am getting over 400fps full screen, checked graphics drivers unloaded/reloaded 3d enabled
