We had a cap in place on landscape. With the cap removed, we see : Yocto - Landscape : 58.4 fps Yocto - Portrait : 16.35 fps Also, for each configuration top reports xorg using : Yocto - Landscape : < 5% Yocto - Portrait : > 20% > > > > I hate to draw comparisons, but our application (Qt 4.8.5 based) running in > WES7 on the same hardware (Kontron COMe-mTT10) sees the following FPS > impacts : > > > > Windows - Landscape : 20.5 > > Windows - Portrait : 20.4 > And what graphics driver are you using here?
