^ Really good points.

So far, the monitor is great. I definitely notice increased smoothness. The only issue is my PC can't sustain 240 FPS. G-Sync is awesome, really makes gaming buttery smooth. One issue I am having though is using RTSS. I can't cap my FPS to 238. The max FPS cap is 200. Any solutions?

This is just a UI issue. The author has locked the UI to a 200FPS maximum cap. I'm sure he has his reasons (he's a bit... weird when it comes to software design.)

You can modify the RTSS profile file directly though. In the RTSS installation directory, there's a "Profiles" folder. You can edit the "Global" file and put whatever cap you want there.

Write the author of RTSS, and link them to this thread -- about 240Hz monitors and the need for framerate capping on them.

Can't find the link, but this has come up on his Guru3D forum section. "Power users" should go through the config file. The UI will probably keep the 200FPS maximum.

But if enough people want the feature, maybe he will concede though. So, yeah.

The forum section is this one:

So is Acer XB252Q better or ASUS PG258Q better?
It seems nobody really cares about the XB252Q.
But unfortunately I just purchased XB252Q and it causes intense eye drains even I'm gaming at 240Hz. The white color in this monitor is so bright that burns my eye and I can hardly see anything in a white background which results in eyes rest every 30 minutes. I already have a LG29UM67 IPS monitor which is fine at 75Hz and still feels comfortable at dimming lights but the XB252Q feels like a light bulb shinny directly toward you and light up the whole room.
And the frustrating thing is that it doesn't change the feel after lowering the brightness to from 29 to 5.

They are both essentially the same. I have the Acer XB252Q and you're right, it is a bit bright at the lowest setting. The way around this is by lowering the contrast. All it does is pretty much lower the brightness.

By MY standards the PG258Q gets pretty dim on the lowest settings but I like my monitors to be about half the brightness of looking directly into the sun.
I can't speak much about the XB252Q but according to tft centrals measurements the PG258Q has a minimum brightness of 116.24 cd/m² which is only slightly lower than 120 cd/m² which is recommended for normal lighting conditions. So it seems that it MAY be too bright by your standards as well. If you have something that you can use as a reference for measured monitor brightness you can use that to get a much better idea of whether or not 116.24 cd/m² is too bright. cd/m² is also referred to as ccd.

(1) Turning on ULMB and then using smaller "ULMB Pulse Width" values, is also another way to get well under 100cd/m2.

-or-

(2) Purchasing a darkening film.
"Neutral Density Film" such as this one. Cut to size, put on your monitor. 4 F-stops is 1/8 brightness, which will kill your nits by 87.5%. If that's too much, try film that does 3 F-stops (1/4 the brightness) or 2 F-stops (1/2 the brightness)

Tom's hardware has tested XB252Q brightness, which is around 106cd/m² at lowest

I bet the Asus/Acer are identical. They did Contrast set to 40 which is also brightness so that probably makes up for the slightly lower on the Acer.
