I also notice this on war thunder, 35fps vs 25fps. On war thunder i also notice that the GPU load is about 75% on 4.10 and 60% 4.11. My upgrade from 4.10 to 4.11 was make oldconfig and choose the recomended new settings. So did anyone else notice any problem? can i check anything first before trying a long bisect to the kernel? Thanks in advance for the help higuita --=20 Naturally the common people don't want war... but after all it is the leaders of a country who determine the policy, and it is always a=20 simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are=20 being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same in every country. -- Hermann Goering, Nazi and war criminal, 1883-1946 --Sig_/chbfi_CIW7byep9Wv9+xMnf Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlkvVgIACgkQrv1jazsMcrP/OACeKOvYkjk9YJo9tycAo1OAaB4Z dFQAoNmjD+LgKcpOdAKxq++XFHDasgeJ =Uo6p -----END PGP SIGNATURE----- --Sig_/chbfi_CIW7byep9Wv9+xMnf-- --===============0335895958== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: base64 Content-Disposition: inline X19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX18KZHJpLWRldmVs IG1haWxpbmcgbGlzdApkcmktZGV2ZWxAbGlzdHMuZnJlZWRlc2t0b3Aub3JnCmh0dHBzOi8vbGlz dHMuZnJlZWRlc2t0b3Aub3JnL21haWxtYW4vbGlzdGluZm8vZHJpLWRldmVsCg== --===============0335895958==--
