Message-ID: <20190609111732.GA2885@amd> MIME-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="WIyZ46R2i8wDzkSu" Content-Disposition: inline User-Agent: Mutt/1.5.23 (2014-03-12) Sender: linux-pm-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-pm@vger.kernel.org --WIyZ46R2i8wDzkSu Content-Type: text/plain; charset=iso-8859-1 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable 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=B0C (high =3D +86.0=B0C, crit =3D +100.0=B0C) Core 0: +98.0=B0C (high =3D +86.0=B0C, crit =3D +100.0=B0C) Core 1: +91.0=B0C (high =3D +86.0=B0C, crit =3D +100.0=B0C) 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?
