Hello, I have a laptop with ryzen 7 4800h and it was using CRU to enable freesync on the new display that I manually put on it. But with the new amd driver (radeon adrenalin 21.4.1) it seems that cru doesn't work. The edid override appears in the registry but in windows the new resolution does not appear and freesync doesnt work. It is as if the amd driver blocks CRU changes. Any solution? I could go back to the previous driver but this one brings interesting updates in graphic options and screen colors. Thank you.

Hello!

I'm sorry if this is a frequently asked question. I tried searching the thread, youtube tutorials, etc but couldn't find the relevant information.

I want to enable Freesync on CRT.
A range of 59Hz-61Hz would be mildly useful for emulation and should work just fine on any given CRT.

Why? If you manually define 59.8Hz and 60.10Hz for the same resolution, Windows seems to choose one and ignore the other.
Bypassing that problem with freesync would be neat. Retroarch already supports using gsync/freesync to emulate games at their original oddball Hz.

But I cannot figure out how to make nvidia control panel recognize my display as freesync capable. I'm not even sure if this can be done with an nvidia card on Windows.

I have one DAC connected by HDMI and another DAC connected by DisplayPort. I've had no luck with either.

I am willing to buy a different DAC, or DP->HDMI adapter, or whatever trivial connector may be called for, but I do not want to downgrade to an older driver, nor do I want to add another GPU to my system.

Is it possible to get freesync working through a DAC? If so, how do I do it?

Thanks!

I don't know. I have a laptop with a Ryzen 5 3500U, and adding FreeSync is working for me with 21.4.1.

It's possible with AMD GPUs, but I haven't seen it done with NVIDIA. Also, AMD requires a 10 Hz range, so you'd have to do like 55-65 Hz.

OK, good to know about the range.

To make sure I've gotten the steps right, what do I do in CRU assuming an AMD GPU? I may not even be doing it correctly at all.

I've tried defining the freesync range, and displayID, but I'm not sure how it all works exactly.

Does freesync have to be defined in the same extension block as the resolutions you're going to use it for?

Should I even need to define a displayID?

Do I need to make the monitor Hz limits match the freesync range, or just define a freesync range that fits within the monitor Hz?

Nvidia knows my displayport DAC outputs VGA and it specifically says "this is VGA", that might be part of the problem, how might I address that?

thank you for your time.

hello!

My Dell Inspiron 3551
Intel HD Graphics Gen7 4EU Valleyview Integrated (SUPPOSED maximum Turbo Boost is 896 MHz)

system (video driver) will crash if i try to up even 1 HZ of refresh rate =>
black screen when applying restart64.exe or system reboot

Could somebody help, please?

Crashing would be a driver bug. Intel seems to have issues with EDID overrides on some laptops.

With AMD, all you need is a FreeSync data block in a CTA-861 extension block and an HDMI data block for HDMI. You don't need a DisplayID extension block. The high end of the range needs a corresponding detailed resolution. The resolution doesn't have to be in the extension block. You need an HDMI->VGA adapter. DP->VGA won't work.

So, I am hearing You saying: "There's a chance!" .. if i find the right driver for my Intel HD Graphics Integrated, which does not crash? Yeees?

Maybe, I don't know if such a driver exists.
