Also worth pointing out is that if you choose a RelWithDebInfo build for OSG or SG and don't specify a null RelWithDebInfo postfix (which is what one of Matthias' lines does >-D CMAKE_RELWITHDEBINFO_POSTFIX="" ) then the SG and FG builds will fail unless you also point them to every individual OSG and SG lib required. By default the generated libs will have -rd (IIRC) appended to their names which confuses things. Thanks to Anders for clearing up that mystery for me the other day!

Re: [Flightgear-devel] Frame rates in git version?
Hi Curt, based on my experience with building FlightGear from yesterday, I'd say that cmake is a great tool and most likely a step forward. But. it does take a little getting used to, in particular the finer details of compiler optimizations, etc etc. I'll try to post my more details about my experiences this evening (I'm not in front of my development machine right now). FWIW, after my initial build, I also got very disappointing performance, but after running a second build with all the settings right, I did got performance levels that I think were even better than what I had before (note, that in addition to switching for cmake, I also installed a complete new distributions) Cheers, Durk On 12 Sep 2011, at 05:07, Curtis Olson wrote: > Sometime in the last week I noticed the Flightgear frame rates on my machine > went to about 1/3 of what they were previously.

[Flightgear-devel] Frame rates in git version?
Sometime in the last week I noticed the Flightgear frame rates on my machine went to about 1/3 of what they were previously. I haven't worked super hard on this, but here's what I can say. When I fire up the Cub at --airport=KANE with clear skies I get: v2.4 = 90 fps (bounces around a bit but usually 90 or above) git = 20-25 fps (same options, same aircraft, same clear skies.) This gets even worse when I fly the f-14b off the Vinson ... even out at sea with just a few clouds it seems like my frame rates are usually less than 20 (12-17 range) with the git version. Has anyone else noticed this or should I be looking for a local build problem? It doesn't seem to be related to my video driver update since v2.4 runs with the frame rates I expect. I recently moved over to trying to build with cmake by default, but cmake hides the compile options so I honestly don't know how to even check what compile options I'm building with now that I switched to cmake. Can anyone tell me how to figure that out? Is there a detailed build log that gets saved somewhere?

I mentioned this change because I'd much rather have a constant framerate (as much as possible) ,and I now have a system that can actually run FG at 30 fps :). On my old system it would go from 8 to 60 depending on scenery , etc . OSG doesn't vary as much, but I have to admit PLIB looks nicer, cleaner crisper textures , proper size splash screen , and so on AND , this was a change I could actually do something about instead of having to ask someone to do it for me :) Cheers -- Syd&Sandy <[EMAIL PROTECTED]> - This SF.net email is sponsored by: Splunk Inc.

I usualy , build both FG osg and G plib from the same release, mainly to check the model compatibility during development. i can confirm the Martin remark: olders fg osg and fg plib where giving almost the same performances. It seems recently (but unfortunately i cannot say exactly when, end of february ?) we have lost that performance regarding fg osg.

Re: [Flightgear-devel] Frame rates
Hi, Hi, Windows XP Nvidea GeForce 5200 ( the weakest); 512 Mb RAM, 2.8 GHZ. Plib: 25- 42 fps OSG: 19-37 fps OSG-Compilation from the 04-18-2007, used the standart aircrafts. With the ufo I can get fps fom 42 to 51. Much improvement since the beginning of OSG in FGFS Seems that it is depending on the operating system. I don't think that is a "believ" if you use Plib or OSG - wasn't FlightGear originally made for Plib? So there might be still a lot of rubbish, which do actually slower the simulation. I can still remember when I start with the release-version 0.9.10 - the fps was horrible. But the developement went on, I could use the CVS-versions and the fps increased- lots of clearence was made in this time. I don't think that a complete change of the renderengine can made in a few months just my two cents HHS --- John Wojnaroski <[EMAIL PROTECTED]> schrieb: > Hi, > > Is there any info/data on FG frame rates with OSG > vis-a-vis previous > plib versions running on comparable hardware? > > Running with the 23 Apr release of OSG and the > latest FG/SG software I'm > seeing frame rates around 22 fps.

[Flightgear-devel] Frame rates
Hi, Is there any info/data on FG frame rates with OSG vis-a-vis previous plib versions running on comparable hardware? Running with the 23 Apr release of OSG and the latest FG/SG software I'm seeing frame rates around 22 fps. The same configuration at KSFO with plib and the 0.9.10 release produces ~65fps. I thought that while the initial performance of OSG/FG when first released was much slower there had been significant improvements over the course of the last few months?? Still a believer in OSG, would just like to see a bit higher frame rate. Might the hardware requirements be a bit higher? Wonderng if I might be missing some subtle points or optimizations in configuring the graphics systems for OSG? Running with Debian X, linux 2.6.17, and the latest Nvidia driver.
