Windows 10 Fastboot hurts Performance "AMD Only??"

[shankly1985]

Seen this video posted today and thought I would also give this a test. So far I only tested Kingdom come and noticed around 10fps difference just having Fastboot enabled. I had the same Apps open at the time I taken the screenshots.
On my Asus Motherboard its very easy to test, if I shutdown PC and restart I enter Fastboot MB LED shows 40 if I restart my PC I boot into Windows without Fastboot MB LED will read AO

Correction
When I said Fastboot in OP I meant Fast start up within Windows 10. Fastboot remains enabled in my BIOS.

FastBoot Off 87fps - Jumps around 87/90fps

Fastboot On 82fps - Jumps around 80/83fps

Fastboot Off

Fastboot On

Fastboot in your bios (LED) and Fast Startup (W10) are not the same thing.

Maybe do some more testing.

They work together, Fastboot in BIOS helps pass info into the OS to help speed up the booting process. If you disable Fastboot in BIOS you loose faststart up in Windows. Least that is how its always been for me on my Asus boards.

They is no need for me to test any futher its 100% confirmed by not just myself but other people that Windows fast start up hurts performance.

On or off makes about 3 secs startup difference on Gigabyte X399 motherboards. But it also has other benefits if you disable you can enter the Bios at power on. With it enabled its impossibly to enter the Bios until its disabled again on X399 Gigabyte mobos.

On or off I have been able to enter my bios normally on all my systems I have owned so far. Z68, Z77, Z370 just to name a few.

Yer know just pressing and holding the Delete button gets you into a modern BIOS these days, works with my z170 board anyway.

I just ran a quick Firestrike Standard test with Fast Startup On and Off..

What a surprise..

On - 12 473 https://www.3dmark.com/fs/15477112
Off - 12 473 https://www.3dmark.com/fs/15477178

Do i need to have Fast Boot Enabled or Disabled in the BIOS.. i have noticed if i disable Fast Boot in BIOS, on my next visit to enable it again, it wont let me. Good job i have a profile set up in my BIOS right

Did you restart after disabling it in Windows? They no need to touch the BIOS setting.
Edit
Maybe only VEGA is affected?

Yep did a restart.. and yea maybe just a Vega thing but i noticed someone asked on that YT video comments thread if it affected Polaris which is what made me wana test it.

Isnt Fast Startup the thing people have been disabling because of Task Manager 'Up Time' not resetting from a cold reboot? Not sure if this might be linked in some way.. but just a thought.

Yeah the Up time is correct because what Fast start up does is basically a new version of Hibernation. So in away the Task Manager time is correct that time is when the PC has full been restarted I.E. no fast start up.

here are my 3Dmark

Faststart up Off

3DMark Score - 7 477
Graphics Score - 7 380
CPU Score - 8 085

Faststart up On

3DMark Score - 7 285
Graphics Score - 7 158
CPU Score - 8 102

So a few percent difference, its a weird one for sure

Fornite Main menu is a good performance test, it pushes GPU into max clocks and is constant.

Fast startup off 92fps
Fast startup on 83fps

In games I seeing around 10fps difference. It really is a weird one, would like to see some Nvidia guys post some results. Maybe it is only a VEGA issue.

 

[shankly1985]

Not bothered to do any before or after tests but games seem a bit smoother on my 290 since turning off fastboot, especially bf 1, doesn't seem to be as many fps drops.

Not noticed any difference in start up time either so will turn this off from now on regardless.

Be great if you could find the time to post a benchmark. Only one game of your choice.
