Problem with sleep mode

[Mario185]

hi guys,

i hope someone could help me. After the update to 8.1 the lockscreen shows up really slow.
I have an Acer W510 Tablet
If the screen is turned off (Just the sleep mode) and i hit the powerbutton to wake up the device i have to wait about 5-8 seconds till the lockscreen shows.
Does anyone have the same problem?
And does anyone have ideas what i can do to fix it?

regards

After a while of searching i have found this: ACER W510 Windows 8.1 graphic driver - Page 2 - Acer Community
So it seems to be a driver problem, and not only for the W510
