Subject: 5.2-rc2: low framerate in flightgear, cpu not running at full speed, thermal related?

Hi!

When I start flightgear, I get framerates around 20 fps and cpu at
3GHz:

pavel@duo:~/bt$ cat /proc/cpuinfo  | grep MHz
cpu MHz		    : 3027.471
cpu MHz		      : 2981.863
cpu MHz		      	: 2958.352
cpu MHz			  : 2864.001
pavel@duo:~/bt$

(Ok, fgfs is really only running at single core, so why do both cores
run at 3GHz?)

But temperatures get quite high:

pavel@duo:~/bt$ sensors
thinkpad-isa-0000
Adapter: ISA adapter
fan1:        4485 RPM

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +98.0°C  (high = +86.0°C, crit = +100.0°C)
Core 0:        +98.0°C  (high = +86.0°C, crit = +100.0°C)
Core 1:        +91.0°C  (high = +86.0°C, crit = +100.0°C)

And soon cpu goes to 1.5GHz range, with framerates going down to
12fps. That's a bit low.

Room temperature is 26Celsius.

The CPU is Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz . I guess it means
it should be able to sustain both cores running at 2.5GHz?

Any ideas? Were there any recent changes in that area?

Best regards,
							Pavel
