Ultimate hack for PERFECTLY smooth running games on the ASUS G751JY.

Hello,

wanted to report here my experience trying to change panel refresh 75Hz -> 60Hz for perfect 60fps/60Hz smooth gaming.




1. Open NVidia panel and go to Change Resolution on the left.

2. Start from 1920x1080@75 and click the button at bottom "Customize"

3. Keep everything as default and change just Refresh rate: 75Hz -> 60Hz




Make it your default desktop resolution.




At this point many games will already be able to choose this screen resolution but not all (some will still use native fullHD @75Hz). To fix it once and forever I just installed new NVidia drivers OVER the old ones (no driver clean-up first) and from that moment on the "Native" resolution for me and NVidia drivers became 1920x1080 @60Hz, probably tricked by the 60Hz desktop std resolution.




Many games run visibly much better because capped at 60fps (e.g. NFS: Hot Pursuit etc.) and look perfectly smooth finally! Moreover you won't have to reach 75fps to see perfect smoothness on screen, 60fps will be enough and demanding games (yes, even with a 980M) will thank you.




P.S.:

Here is a video on YT with one guy explaining how to make a custom screen resolution through NVidia control panel: https://www.youtube.com/watch?v=HlERjmkBoHg

I concour with your statement. Makes total sense in a way...

I see many posts on this forum in regards to the black screen when they start up Windows 8.1. This, in many cases, is due to people cranking up the panel refresh to 100Hz, even at 75Hz can be an issue. When you initially set it up, it's all up and running smooth, however, when you start up your machine it will pop a black screen.
This is one of many reasons why the new, or latest NVidia drivers kicked back to the classic refresh rate of 60Hz.

After reading several threads on this forum I set my refresh rate to 100hz. Nvidia gives a warning notice, and I am starting to rethink my decision of setting it to 100hz. All that I have read on the topic suggests that every panel is different, and while one laptop may work for years at 100hz, another might crash/burn at 75hz. For what it's worth, I've had no problems at 100hz so far, but I'm thinking of scaling it back to 60hz. YMMV I guess.

I think what this post is about is for a release or two nVidia drivers set the G751 panel to 75Hz, the post explains how to get 60Hz back and explains how this can smooth out the frame rate for games hard coded for 60Hz.

This should would not be of note for most as I would imagine most people are no longer running a driver release with the 75Hz default, albeit still useful if you still are for some reason.

ROG15,

For what it is worth I've been on 100Hz since the end of Nov., no issues or complaints. Of course you have to weigh the risk vs reward yourself.

Yes, sync'ing game fps to video refresh means perfect smoothness. My model, even after a pair of nVidia driver changes was at 75Hz by default (LG Display LP173WF4-SPD1) and I noticed many games didn't look very smooth compared to my other gaming notebook (MSI GX660 + AMD 7970M) with a gorgeous AUO B156HW01 V4 at 60Hz. One of the most evident examples was NFS: Hot Pursuit runnig visibly worse even if fps counter was stuck at 60fps.... For this reasons I've reset it to 60Hz which is optimal for silky smooth gaming. Any other refresh (75, 90, 100Hz) and you'll see a very minor improvement for your desktop but much worse "smoothness" while playing games. Perfection is 60Hz and games at 60fps. At default I was forced to reach 75fps to see perfectly smooth graphics (because the panel was 75Hz as I said) and some games on Ultra were not even able to reach that frame-rate. 60Hz, hence 60fps is really the best compromise with the best results.

For desktop only you mean? Yes... and keep 60hz as native (for games).
100Hz for gaming means your in-game frame rate must be solid 100fps, if you want to see true smoothness as perceived by human eye.
I've seen there are still many users out there that don't understand this. They just think the higher Hz the better always, and unrelated from Hz, 60fps = automatically smooth gaming, which is not if your display frequency is not equal to the fps.

You can have 120Hz refresh (more relaxing for the eyes), but with 60 fps games (and in general non-120fps games) will look worse than 60Hz/60fps. Your eyes will notice it's not exactly "smooth".
