Re: [Flightgear-devel] Strange GPU behaviour
I'm not sure if the settings suggested there still work with current drivers, but it's a start. Nope - the available options for the newer driver are quite different. Also, the problem is not that the PowerMizer defaults to adaptive - it doesn't, I can change its setting. It just never makes use of performance levels 2 and 3 - which is what I'd need. Hooray came up with the idea that power management might have to do something with it - judging by other people's posts, the behaviour that the performance level never goes all the way even with prefer max. performance set seems to be normal when running under battery - so does the driver perhaps think it runs under battery even if in reality it doesn't? Unfortunately right now I've gnome3 installed which has zilch in terms of configuration of power management, so I probably need to wait for Monday to get the bandwidth to install KDE and see if that makes a difference. Or is there a quicker way to test this? Just to say that if you have a serious cloud coverage (with or whithout rembrandt) you'll never get more than 30 fps and more likely 15 fps. It's abysmally bad - worse than with my old GPU - I'm seeing like 3-4 fps in minimal atmospheric light scattering, no clouds. The GeForce 8600M used to crunch this with 16-20 fps. :-) So it's definitely not just FG performance. * Thorsten -- Monitor your physical, virtual and cloud infrastructure from a single web console.

Le 23/11/2012 20:03, Renk Thorsten a écrit : I guess I need some help here... I've finally managed to compile FG on the new computer, then copy my FGData here, and... it works. But the framerate is abysmally bad. Hi Thorsten, Just to say that if you have a serious cloud coverage (with or whithout rembrandt) you'll never get more than 30 fps and more likely 15 fps. Here, core i7-3Ghz-16 MB RAM, GTX 680-2MB VRAM, 1920*1200px, you can set a 200 km visibility, every shader to the max, complex models like the f-14b + the Vinson, and fly around SFO with a steady clamped 50 Hz. But as soon as the clouds start to cover the place the fps drop to 20 or less. So I never fly with the cloud slider set to the max. CPU/GPU power doesn't do much in regard to clouds rendering. Since I got this new powerfull box, everything got *really* improved but clouds rendering. Advanced weather cloud coverage seams to be a bit faster than the visually equivalent global weather cloud coverage (just talking about what you see from the cockpit when inside the weather, that is plenty of grey everywhere). Isn't that you are seeing ? Alexis It doesn't seem to be Flightgear though... When I open the NVIDIA X Server Settings while FG is running, I can see the various performance levels with Graphics, Memory and Processor Clock speed. The problem seems to be that I never get above performance level 1 which gives me 73 / 324 / 147 Mhz, whereas 3 would have 597 / 1500 / 1195. So no wonder the framerate is low. I do see changes in performance level from 0 to 1, and I can change the Preferred Mode from 'Adaptive' to 'Prefer Maximum Performance' - the latter option locks me at level 1, whereas the first option occasionally clocks down to level 0. Now, I have no idea what is going wrong here. There's no second GPU onboard, i.e. I'm not having an optimus problem, I'm getting to see one device and one device only. The driver is the 304.60 native NVIDIA driver obtained from rpmfusion as recommended by Fedora. The graphics cards is the GeForce GTX 670M which is listed as being supported by that driver. The distribution is Fedora 17. The thermal sensor is of the opinion that the card is quite cool (42 deg), so I'm not seeing heat problems here. So for some reason, the driver fails to bring the card up to the serious performance levels, and I have no idea what the problem could be. Has anyone any idea where to look for a solution? I don't really want to swich to Windows to run FG... * Thorsten -- Monitor your physical, virtual and cloud infrastructure from a single web console.
