The thing is, I've been meaning to replace my entire setup and am thinking about getting at least a 144Hz FreeSync monitor so... just in case.

The only way to know is to test the lag.

Is there any way to bypass standard resolution 123hz refresh rate cap? I want to set it to 240hz.
Or maybe someone will have another solution for my problem?

Situation looks like that - one certain game forces itself to work in "standard resolutions" listed in CRU. When I shut it down and quit to Windows desktop I have 240hz from detailed resolution again (information important for later)

But...
When I delete all "standard resolutions" that game finally works in detailed resolution and I get stable 240hz refresh rate - sadly, when I shutdown that game and quit to Windows desktop my refresh rate is somehow stuck to 88hz and I don't know from where it got that value - I didn't seen it anywhere in CRU.
Somehow launching and quitting some different games or executing "restart64.exe" reverts desktop refresh rate back to 240hz - until I launch and shutdown that problematic, mentioned before game again - it is messing up desktop refresh rate again.

I'm out of ideas how to get 240hz in that game without any issues.

Thanks.

There's no way for the data to represent refresh rates outside of 60-123 Hz for standard resolutions. You have to use detailed resolutions for other refresh rates. There's nothing special about the way standard resolutions work. There's no way for a game to only support standard resolutions. You didn't give any details about what's actually happening, only what you think is happening. You didn't mention what game, what monitor, what GPU, what resolutions, what CRU shows. Export a file using CRU and post it here.

Intel doesn't provide a way to add custom resolutions on laptop screens with 4000-series GPUs.

You would have to ask Intel why their driver limits custom resolutions on laptop screens.

Keep reporting it with every driver version.

I did 78hz before, it's been about 1 year but i cant again 1024x768 75hz and 78hz

Hi, I've been trying for a while to make my VRAM idle at 165 Hz but I haven't been able to yet.
I have an RX 5700XT connected via DP 1.4 HBR3 to an MSI Optix MAG274QRF-QD (1440p/165Hz) and at 60/120Hz the VRAM clocks can properly idle at 200 MHz but when set to 165 Hz it goes all the way up to max clock speed (1740ish MHz). Under "detailed resolutions" I only have one for 60 Hz so I edited the 165 Hz one under "extension blocks". My vertical blanking is set to 22 and I can only raise it until 65 before the frequency values go red. Also all the timing options give me a red "refresh rate".
Am I doing something wrong?

Thanks so much for the fantastic utility!

Quick question... I'm using an LG 34GN850 which is 3440x1440 (native) and supports 60, 100, 144, and 160 Hz refresh rates. It does not support 120 Hz.

However, when I use CRU to add custom resolutions that are higher (3456x2160 with 60 and 120 Hz), the Nvidia control panel automatically adds 120 Hz for 3440x1440.

Is this a bug? It seems like Nvidia assumes if my monitor supports a higher resolution at the same refresh rate then it must be supported at a lower resolution.

If I test 3440x1440 @ 120 Hz, the monitor freaks out so it really doesn't appear to be supported which seems very strange but regardless...

Another reason to avoid AMD, I guess.

I went from a GTX650Ti to an R9-380 and right off the bat I noticed that you can't force half-vsync from the drivers. To add insult to the injury, the force vsync option in the driver is broken, at least in my experience.

I was thinking about moving to Polaris (RX580 8GB) but then I learnt that RSR is exclusive to RDNA based GPUs, whereas even the 750Ti supports NIS (their answer to RSR/FSR1).

Needless to say, their GPU division has taken a back seat after Lisa Su. It's competitive, sure, but no match for Nvidia when it comes to driver stability and overall level of 'polish.'

Long story short, if you want proper frame pacing, go Nvidia. AMD shouldn't even be a consideration.

Sorry for the rant. I guess I wanted to vent!

@ToastyX First of all I'd like to thank you for this super beneficial tool, it is much appreciated!

Secondly, because I couldn't find an answer for my specific question I wanted to ask it here.

Since the monitor I use has variable refresh rate feature I have tried to use it but couldn't succeed.
Whenever I activate the Gsync from the Nvidia control panel and start a game or 3d application screen starts to blink and turns black.

According to the data sheet of the monitor following are the frequency ranges:
*DP (v. 1.4): fh:15~120 kHz, fv:24~75 Hz
*HDMI (v. 1.4): fh:15~120 kHz, fv:24~75 Hz

Then by using the CRU I changed the default vertical frequency range from 24-75 to 48-75 and the problem is fixed.
But my question is the reason why the monitor can't handle the 24-75 range for variable refresh rate is because the monitor has some sort of a fault or because the connection cable I use, or the variable refresh rate range is not as broad as it is specified in the data sheet?

The Gpu I use is Nvidia Gtx1080, and the monitor is connected with a Displayport cable which's version I assume is 1.2.
Also, it should be noted that the default Freesync range in the Data blocks section is 48-75.

I would be appreciated if you could help me about it.
Thanks in advance!
