Discretizer on Vista
After installing a new driver (ATI Catalyst 8.5), OpenGL speed was fast. OpenGL with Catalyst 7.4 was unacceptable slow.

OpenGL speed enhancement
Now it's possible to view bigger models with a high frame rate. Selection is also more rapid. This was achevied by the use of OpenGL display lists. Huge improvement. Currently only available via sourceforge SVN.
The 1,200,000 cell corkscrew is now editable thanks to the enormous OpenGL speed encrease. Time to read the file is now only less than 10 minutes compared to the 1.5 hours before. Number of surface cells on display is 49x49x2+ 49x499x4 = 102,606
Big mesh test
To really test the new mesh creation speed I increased the number of cells in the "t20_screw.dtz"-file to 50x50x500 nodes (1,198,099 cells). It took 1.5 h to read the file, 6 hours to create the volume mesh and 14 hours to calculate 100 iterations with simpleFoam. The volume mesh speed took much longer time because the computer did a lot of swapping (an ancient Pentium4 2.4 GHz with 1.5 GB RAM). Y-plus is about 30 in this calculation.
