72hz monitor questions

[lorcav123]

I have Samsung C27F591 and I set it up to 72hz. Many games doesn`t support 72hz so it will lock with vsync my fps to 60 and because of that I will have stutter and screen tearing.

For example Metro Last light vsync is 60fps. Would it be good to turn off vsync off and in set frame limit in graphics card settings to 71? Any drawbacks with this settings?

Will you tube video stutter if I watch it with 72hz? Is it better to put it to 60hz frequency?

We don't know your system specs but if your system and graphics card are powerful enough to push the fps to a steady 70~72 fps turn off vsync and use RTSS to lock the fps @ 70~72fps.

Ati 7770 (soon I will buy much stronger Ati - Polaris - Vega )
Win10

1) I was anyway thinking ti using RTSS because of this (seems much better to have this open form startup than to change frequencies constantly in windows settings):

Is it necessary to lock fps to 1 fps below monitor frequency, in this case it is 71fps?

So when using RTSS in that way I won`t have any tearing, input lag will be normal and all other variables (I tried Metro LL, vsyn off and frame limiter to 71, so far so good) ?

Would also help if I for older games (when vsync off) use enhanced sync (I think that is the right name) so I don`t have to change frequency too often? Let say I turn off vsync and activate freesync + enchanced sync?

2) Also I have one more problem with this monitor:

Freesync ON in monitor OSD: - When I turn on PC no signal until welcome screen (when welcome screen is shown in left corner there is a HDMI input sign)

Freesync OFF in monitor OSD: - I can enter BIOS and see whole boot procedure

Why is that? Is it because motherboard (I will change it soon)? Maybe because my current gpu doesn`t support freesync?

Other problem is that after I turn on PC and boot into windows I will always hear a "device connected sound" and after that on my monitor there will be big number "1" like it is identifying display. Any solution to this?

Yes turn off vsync and enable frame pacing

What driver version are you using?

@fullinfusion might be able to add additional help on this

Why don't you try the new enhanced sync? It works like a charm on my 7750.
Set it in the driver and keep vsync disabled in game settings.

2nd this, Rx 480 on a 60hz (72hz o/c.. Samsung, model in specs) and it works perfectly. Also using enhanced sync on r9 390x and a 60hz benq. I used to use CRU on my Samsung monitor to achieve 72hz until enhanced sync came along

There are your 2 witnesses to use that trick, so do it.

So if I understood:

- for demanding games:

freesync + enchanced sync - vsync off

- for old games

frame rate target control - vsync off (if it can`t lock fps at 72hz)

I found in this post from AMD_Robert that freesync is not a good thing to be used with frame rate target control

What is the name of enchanced sync in Radeon settings? I think I have some older drivers without that option but I belive it will work when I update so I will wait for new GPU that I will buy in less than a month.


Any solution for invisible boot procedure when my freesync in on in monitor OSD?

If the game absolutely won't run faster than 62Hz (they're never locked to exactly 60, always a bit above) then set the monitor refresh to 60Hz and use vsync or enhanced sync.

This business of manually setting the max game fps to a bit below the monitor and not vsyncing is idiotic. All you do is generate some very unpleasant stutter.
