Object graphics under Linux: are they supposed to be that slow? [message #29066]

Hi guys

I have recently been considering a switch to from Windows to Linux for
various reasons that I won't go into here. I have set up a dual-boot system
on my PC and, as of today I have IDL running on both OSes. I'm afraid it's
been a disappointment. I mean, I've used IDLDE on another Unix system so I
wasn't expecting too much of it. (I planned to use IDLWAVE in any case). But
object graphics rendering on the Linux side is unusably slow! For example I
have an object-graphics animation example program that presents a series of
25 x 25 IDLgrSurface objects. It runs along at a tolerable 15 frames per
second on Windows but barely manages 2 frames per second under Linux. Using
software rendering on Linux seems to speed things up slightly, but not much.

The PC has a Pentium 3 800 Mhz processor with an Intel 815 built-in graphics
controller. I run 16 colours, 1280 x 1024 on both OSes. The Windows OS is
Windows 2000 and the Linux one is Redhat 7.2 (kernel 2.4.7-10). The system
has oodles of RAM and disk space.

Is there anything I can do to improve OG performance under Linux?
