I have the default tickless Debian 5 kernel for 64 bit systems.

Code:

$ cat /etc/debian_version
5.0.1

Code:

$ uname -r
2.6.26-2-amd64

Code:

$ grep HZ /boot/config-2.6.26-2-amd64
CONFIG_NO_HZ=y
# CONFIG_HZ_100 is not set
CONFIG_HZ_250=y
# CONFIG_HZ_300 is not set
# CONFIG_HZ_1000 is not set
CONFIG_HZ=250

Why do you mention Hz? I thought we were talking about FPS.

Could you elaborate on your statement that custom kernel is required for 1000 FPS.
