Can anything be done about double vision / blur effect?

General Discussion
1

Hi, basically I’ve been having an “issue” that really, really bothers my eyes. If I move my cursor fast, I get like a “double vision / blur / ghosting” type effect. Is this just… normal? Is this something I could fix with a G-Sync monitor? Something to do in the OW graphics settings / nvidia control panel?

Here’s an example:
(I know there’s a bit of tear too since VSYNC is off.)

Looking at this makes me nauseated, and while I don’t sit there and shake my mouse back and forth, trying to scan for targets or doing 180 flicks really bothers my eyes.

I see nothing wrong with the video, albeit I’m on mobile.

What you describe sounds like LCD motion blur. Check the following website see if you can repeat the issue: TestUFO: Chase

If you’re using a TV rather than a monitor as a panel, there’s a bunch of options one should check.

Your monitor is the issue, its response time is too slow so you’re getting ghosting. There’s no issue in the recorded video or the game itself in this respect.

get 144hz monitor and maintain 120+ fps

Okay, I guess I misused the word ghosting. Basically, see how when I go from side to side, the one sentry turret UI indicator basically becomes multiple? Like “double vision”

The video is exactly how it appears on my monitor. Maybe what I thought was a problem is just normal. (Checked on my laptop and phone)

I’ve got a 144hz and keep a steady 144 fps already

Thanks for showing me the test. Looks like the consensus is that it’s just how it’s supposed to look when I move fast like that. I’ve check out a few videos from streamers and it seems to be the case. Oh well :confused:

I’ll bump this topic because I already talked about it very briefly but without much effect.

TL/DR: This is not blur, it’s actually the EXACTLY OPPOSITE PROBLEM, which causes a problem even more distracting then blur for some, this “gaps” between frames. The solution is Blizzard introducing an good Motion Blur per Object to solve this, like Doom 2016 does.

Motion blur is one of those “stigmas” on gaming community, like gyro aiming for example. But it is actually NEEDED to make motion “believable”. The “soft solution” for this is going for higher refresh rate and higher FPS, This will rise the cap that this effect will start to happen (you’ll need to pan faster the camera to see gaps).

This happens because the frames from games is “instant snapshots”, and our eyes doesn’t actually “see” in frames in the actual “reality”. On the real world, you see an infinite amount and your eyes naturally “blur” then. In movies we “simulate” this effect changing the shutter speed, so the “gaps” between images are glued together in a way that our eyes can perceive and correlate as “natural”.

You can easily notice this changing the “shutter speed” on videos. The faster you’ll go, the more “jittery” the image will be. This can cause some artifacts like syncing the RPM from an helicopter rotor and the shutter speed from your camera. In the recording, the blades will be “static”. It is easy to find videos about it, but I can’t link it here so you’ll need to search.

Since we can’t have “infinite” amounts of frames on games, the only solution for this is a combination of various things.

First, this sounds “strange”, but you actually want the least amount of MOTION BLUR caused by your panel, in other words, fast response time and higher refresh rate, or a good MBR implementation. This type of motion blur (sample and hold effect) will not help to solve the gaps and it will actually make then even more annoying.

A high enough framerate to have a high sample rate for…

A good per object motion blur. The best example that you can correlate with Overwatch is Doom 2016. Just set motion blur to the highest quality and turn on it even on the “low” amount. You’ll see this problem doesn’t happen, and the movement is very focused, natural and “glued” together.

I can talk much about this, but Digital Foundry already made an EXTREMELY good video on the subject, you can search for [Tech Focus - Motion Blur: Is It Good For Gaming Graphics?

And a good site for fast tests for this type of problem is this: [UFO Test: Ghosting testufo dot com.

Go to the Ghosting / Pursuit Camera test.

For curiosity, try UFO separation on 160 pixels and speed at 7680 pixels per sec. If you’re into a 240Hz Panel you’ll se a bunch of static “UFOs”. This is a perfect example why id doesn’t matter how “high” our FPS or frequency is, to solve this problem and make motion “believable” we NEED a good implementation of Motion Blur.

So BLIZZARD, PLEASE. Do an option for this , in Overwatch we have way to much movement and almost instant acceleration, so this problems pop like no other place. It’s EXTREMELY distracting. At least bring it an option for Overwatch 2.

Ps. I know a lot of people aren’t “prepared” to discuss motion blur in games. It’s ok, a lot of then doesn’t actually understand what it is. For anyone who still “hate” motion blur. I can’t recommend enough the video from Digital Foundry and Doom 2016.

A little more info that I think it is important for people even more interested on this topic, search for the blur-busters-law-amazing-journey-to-future-1000hz-displays-with-blurfree-sample-and-hold article on blurbusters.

There, he explain this is called the “Phantom Array Effect”. In his own words:

"

But I Also See Stroboscopic Effects at Full Frame Rate Too!

This happens when you do fixed-gaze situations. This is also called the Phantom Array Effect. Stare at the middle of the below animation, the [TestUFO Mouse Arrow Demo].

Adding artificial motion blur (GPU blur effects) or camera motion blur (slow shutter) can fix this stroboscopic effect.

Unfortunately, there are many situations where we don’t want motion blur forced upon us by the display above-and-beyond natural human vision blurring. This includes virtual reality headsets. Oculus and other manufacturers found that low-persistence reduces nausea in virtual reality. They cannot add additional motion blur without increasing nausea. So stroboscopic effects are currently the lesser of evil for most people.

During our [true 480 Hz monitor tests], stroboscopic display effects were still visible even at 480 Hz!"

Since we’re WAY to far from thousands FPS and frequency rate, the better solution for those who are extremely sensible by this effect is the addition of a proper Motion Blur per object on the game. This is the reason why I advocate at least the implementation of it.

For those who don’t like Motion Blur or feels nauseated. Just turn it off. I personally feel more nausated with this gaps.

you came too late OP prob throw up all over their house or something

But still is a subject that should be addressed. Motion blur is a very “divisive” topic in gaming because most people actually don’t understand these things, like the OP.

He’s misinterpreting this “double vision” as “blur”, and I’m sure a lot of other people thinks the same, but can’t explain because they don’t know about “stroboscopic effect”, “wagon-wheel effect”, phantom array effect. All problems tied together because we have way to low FPS and frequency displays to avoid this in fast panning situations (which happens a LOT in Overwatch).

Back on the old days, 2D games didn’t suffer much from this because the objects on the screen didn’t move fast enough to be noticeable most of the time, and of course, 60FPS was the “norm”, but you can see like this example of Sonic watch?v=9kOAdhUlkt0 in a 30 FPS video seems VERY jittery.

This is a problem who should be addressed. I’m pretty sure a lot of people feels this effect but can’t explain “what it is”. A simple and GOOD motion blur implementation should solve this for then… And for those who are sensible by the artificial motion blur effects, it could be just turned off like now =).

I have a Gsync monitor and can’t see anything. And I switched to a non-gsync monitor. Can’t see anything. Try it on other games and see if the same thing happens. If so, ur monitor probably has a motion blur thing or is just broken. I’m not a professional though.

More about the MS on the panel I think. I got a 1440p/144hz 1ms wqhd TN. Only thing I ever get ghosting is in Star Citizen and I dunno why >: (

Again. This is NOT related as a display problem. You can have a 240Hz fast panel and STILL suffer for this problem. It’s just a side effect about how gaming as a whole work. It’s the same thing as recording at a fast shutter speed and moving the camera very fast. This can happen with any display, even CRTs. But CRTs by nature will have a “sharper” instant image because of the flickering.

The problem the OP is describing is NOT motion blur.

Does people even read what I posted? This is the reason why the devs should just add an option for a proper implemented motion blur effect.

This is very easy to understand if you just take a picture from the screen using a slow shutter speed (like 1/20). Just see here: htt ps://i.p ostimg.cc/0yf4K3fn/W hats-App-Image-2021-01-15-at-15-54-54.jpg

I’ll just copy and paste an excellent argument why this is a problem that should be addressed by Blizzard, taken from an article from Blur Busters.

" This Effect Happens In Video Games Too!

Not everybody is sensitive to in-game stroboscopic stepping artifacts… Different people have different priorities when it comes to displays. Different people are sensitive to different display limitations. Perhaps you are more sensitive to flicker than tearing. Or more sensitive to color than brightness. Tearing versus stutter. Latency versus motion blur.

…However some of us are extremely sensitive to this artifact! A graphics artist or home theater enthusiast may have a strong preference to excellent color quality. However, other of those of us have a strong preference to superior motion quality with less display motion blur and stroboscopic effects.

Now, we present some real world examples, staring at the crosshairs in a first-person shooter game such as Counter Strike: GO, a very popular competitive video game in esports:"

For those who don’t understand. It’s easier to notice if you just focus on the crosshair and use your peripheral vision on the background. It will be much easier to notice the “gaps” since our peripheral vision is more sensitive to motion.
