I run qemu from git with such command:

qemu-system-x86_64 -nodefaults -m 4096 -smp 8,cores=4,threads=2,sockets=1 -cpu 
'kvm64' -device usb-mouse -M q35 -vga qxl -no-hpet -boot once=c,menu=on -device

-device ide-drive,bus=ide.1,unit=0,drive=drive-ide1-0-0,id=ide1-0-0 \
-spice port=5930,disable-ticketing

Before guest (Windows 7) reboot, videocard works in 3D mode with full
frequency. But after reboot videocard works in 3D only with powersafe
frequency. Then I must reboot host for recover gpu clock control.
