Some questions regarding Adaptive Sync/Variable Refresh Rate
Posted: 12 Mar 2020, 15:37
First of all, let me say that I've been lurking this website for quite some time and I think it's a great source of reliable and useful information. Getting to the point, I'm in the market for a 1440p IPS monitor and I think I'll be settling for the ASUS PB278QV, which has a quite narrow Freesync range of 48-75 Hz, but I don't need high refresh rates and its price is adequate. I mostly play single player games (which I usually cap at 75-90 fps with RTSS or Radeon Chill on my current 60 Hz monitor) and emulators (capped at 30 or 60 fps).
I have never used a Freesync or G-Sync monitor, I understand its purpose is to prevent tearing and stuttering, but I've been researching about it and I've seen some complaints, notably:
I have never used a Freesync or G-Sync monitor, I understand its purpose is to prevent tearing and stuttering, but I've been researching about it and I've seen some complaints, notably:
- Flickering/shimmering, most likely caused by brightness variations produced by inconsistent refresh rate and Low Framerate Compensation.
- Ghosting/overshoot, most likely caused by the response time not adjusting accordingly to the refresh rate.
- Input lag and a less snappy feel.
- Can Freesync negatively affect the gaming experience?
- Does it degrade image quality, outputting an inconsistent and innacurate reproduction?
- Is Freesync worth it at a range of 48-75 Hz? Would it give a smoother experience if I play at a fixed framerate of 60 fps?
- Is the input lag noticeable or something to worry about?
