What is better? Question 100hz vs 120hz

Post by urut » 30 Apr 2015, 06:36

Hi, i've got question. I playing some games but with my hardware i can do only 100-110 fps, sometimes 120fps but dropping down. Is it better to play this game with 120hz, lightboost 10% and contrast 37 with 100-110fps (dropping :<) or play with 100hz, lightboost 10% and contrast 37 with 100-110 fps (always, 0 drop below 100) ?

Image

Is that 0.3 ms (from 100hz 10% and 120hz 10%) are changing something?

It's better to keep your refresh rate equal to your frame rate. The difference between 100 and 120hz is very minimal. If you keep 120 fps with rare minimal dips into 110 fps most of the time, then 120 hz is fine. But if you spend half the game at 110 fps, then 100 hz/100 fps is better.

I can use 120 fps/120 hz in black ops 2 and keep 120 fps with 4x AA constantly, but if I enable FXAA and adaptive anti-aliasing in the control panel (because there's noticeable shimmering on alpha textures/foliage if I don't have adaptive AA), I get 105-110 fps drops on some maps a lot of the time, and those drops are annoying and affect my aim. If I am at 100 hz/100 fps, it NEVER drops under 100 fps and the game is more enjoyable. That's worth having a tiny bit more input lag (I use vertical sync on).

Vertical sync stops screen tearing. But it adds input lag as a result. This input lag is usually negligible at 144 hz, but is massive at 60 hz.

You can keep it off if you can use a frame rate limiter to cap the frame rate at the refresh rate (this can improve input lag) but if your frame rate EXCEEDS The refresh rate, you will get ugly retrace vertical lines due to the screen being refreshed at different times during the frame.

Using a FPS capper with vsync off to cap the framerate at the refreh rate can still give screen tearing from time to time, however.

Hm, and what about 100hz with lightboost 10%? If i've got 110-115 fps stable? ;d Is it better than 100hz lightboost? (in Chief table is nothing about 110hz blur ms) :P

gsync would be perfect for your situation :P

You're asking repeated questions.
You know you can test this yourself and try it?

And why are you trying to use Lightboost when you have benq blur reduction with Vertical Total 1500 tweaks?
Do you have version 4 firmware installed?

With V4 firmware, benq blur reduction looks much closer to lightboost quality (you need to use the AMA high toggle after blur reduction is enabled) compared to V2, which looks much worse (the AMA toggle on V2 makes things worse, not better).

Lightboost does have very good motion quality on the XL2411Z, but the contrast drops massively and the gamma drops to around 1.8 (from 2.2) and you can't adjust it easily (needs calibration).

I've got v1 firmware :(

I dont use BBR cuz when i do VT trick, on desktop is bugged OSD (1920x1080@60hz) but this didn't work in games. In games i've got 120hz in osd (idk why this didn't work, i've got gpu scaling)

read this article. The OSD is NOT bugged at all. The scaler is confused by the vertical total change (vertical totals affect the resolution it tries to sync to) and thinks the horizontal and vertical resolutions are different (increasing the vertical total indirectly increases the vertical (height) to the monitor's scaler.

Because the scaler sees a different resolution than the active resolution, it uses the 60 hz backlight pulse widths for strobing. It's not really running at 60 hz.

Anyway you can update to Version 4 firmware with Ubuntu. I'll link the instructions.

Others are here.
The instructions I posted on the last page of the Linux thread work perfectly. I never in my life saw Linux before, and even I was able to update my XL2720Z to V4.
