[Flightgear-devel] Recent shader stuff vs 2.4

[Tuomas K. <tuo...@gm...>]

Hello.


I was talking about this on irc before as well. I am testing stuff on an
older macbook running Ubuntu, and with fg 2.4 I could set the "enable
shaders" master switch in rendering options to off, and without 3d clouds I
got about 25fps, which was ok for testing panels and developing gauges etc.
Whenever I just checked the toggle to enable shaders, but all sub-options
off, my fps dropped to about 4.


The recent shader options revamp seems to put me in the "4 fps" mode even
though I set everything to minimal. I wonder what changed there to hog the
GPU performance. Sure, it's an old and crappy i915, but the change is
pretty significant, and the options I am setting are basically minimal
eyecandy to get max fps. Anyone got a clue why this happens?
