Hi David, I presume it's the geometry shader support that is causing this. Try to disable technique number 8 in landmass.eff regards, -Fred -- message original -- Sujet: [Flightgear-devel] Bug: landmass effects cause system crash in today's CVS FlightGear De: David Megginson david.meggin...@gmail.com Date: 05.04.2010 22:36 When I enable landmass effects in a FlightGear binary built from today's CVS (and using today's base package), my entire computer freezes and I can reboot only by cutting power. Urban effects still work, however. With a binary built from the March 13 CVS, I can enable landmass effects -- still using today's base package -- with no bad effects. I'm using Ubuntu Lucid, with this card info from the X log: (--) PCI:*(0:1:5:0) 1002:9612:103c:3045 ATI Technologies Inc RS780M/RS780MN [Radeon HD 3200 Graphics] rev 0, Mem @ 0xc000/268435456, 0xd230/65536, 0xd220/1048576, I/O @ 0x5000/256 and (II) Module glx: vendor=FireGL - ATI Technologies Inc. compiled for 7.5.0, module version = 1.0.0 All the best, David -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
