30fps but still blurry panning (video)

[ols500 43]

Hi I cannot solve this issue... It looks as if its some kind of motion blur! Very annoying. Any ideas?

 

Heres a video: 

 

BenQ 60hz GW2270 monitor

Vsync, FPS unlimited

No external lock.

 

Thanks, Ollie.

Personally not seeing any blur, so I suspect that's a local issue that can't be recorded. You're saying 30FPS in the title, yet your overlay is reporting less than that, barely holding 24, which could create a very unpleasant and unsteady image. Plus, some monitors under certain conditions can be prone to creating a motion blur effect due to low refresh rates, high image latency etc. you could possibly also have settings enabled on the monitor itself that makes it worse, like an overdrive setting.

Do you mean "AMA"?

Possibly. Each manufacturer has their own names for these functions. I assume that's BenQ's name for it.

AMA has

High

Premium

 

However, I see no difference between them.

Its bizzare. I lower the settings and get the same FPS, CPU and GPU usage do not change. You would think they would increase with higher settings, but they don't. They stay at around 50% CPU and 40% GPU.

Yeah, it was just a possibility. Like for example, you see someone here in the comments, mention that AMA can introduce a lot of ghosting, which could easily be perceived as a sort-of motion blurring effect: https://old.reddit.com/r/Monitors/comments/5l0v3i/do_i_need_to_have_ama_on_to_get_1ms/

Other than that, someone else would have to chime in on the performance issue, as that seems like a peculiar issue indeed.

Ok thanks for help anyway. Let's see who else replies 😄

I don't see anything abnormal in your vid, but then again maybe I am not seeing clearly...I just worked 11 hours.  It's also Youtube, maybe the capturing didn't translate the blur well.

Since you refresh at 60 hz, are you using RTSS Scanline x/2 or whatever the 60hz guys are using these days?  Supposedly it is presently the hot ticket to smoothness for 60 hz users.   If you are not -- perhaps that is the problem. 

You are not able to maintain 60 fps in that situation (none of us could), and THAT is a big problem kemosabe.   In the sim, with your 60 hz refresh rate, you would have to be able to maintain 60 fps for nearly-complete smoothness.   With RTSS, as I understand its Scanline x/2 option, you would only have to maintain 30 fps in that same scenario, to get smoothness -- a lot easier than maintaining 60 fps.  RTSS = RivaTuner Statistics Server.

I'm sure someone else will come along and add further wisdom.  I don't personally use RTSS as I refresh at 30 hz, so I'm not the most qualified person to comment on it.  Hope that at least gives you another angle though.

I watched your video in full screen, and I think I know what you're experiencing. It seems like the image simply can't keep up with the speed of the panning. I'm seeing the same thing in my setup. My frames are locked at 30 by using vsync on a 30Hz monitor.

I've tried every possible setting I could think of both on my computer and the monitor and haven't been able to get rid of that effect. I came to the conclusion that either my monitor is too cheap to handle that motion or that 30fps is simply too slow to keep up. I've kind of gotten used to it anyway, so it doesn't bother me all that much anymore. I wish I had a solution for you.

Same thing for me, I think my monitor just isn’t good enough to make it clear panning, Like you I've also gotten use to it, but to the OP, could always be worse, remember when virtual cockpits weren’t even a thing and all we had were 2D flight decks in flight simulation lol...

hopefully someone has a solution!

Just an observation, but if you can see this effect in a video it can't be anything to do with your monitor.

I can't see anything wrong with this video, but I suspect it's just that fast panning reveals the quantization of the image. Presumably this is why fast panning in films was traditionally frowned upon. I expect you can calculate the relationship between frame rate and noticeable quantization quite easily if you think it through.

Hi I'm at the gliding club right now so I cannot test anything but here is my thoughts:

I have RTSS and tried 2x scan line with 30fps locked in P3D. Makes it even worse. I have overdrive turned to premium on my BENQ monitor which helps a little. To run 30hz you need a 4K monitor, which in turn requires a more powerful GPU than my 1060. On my ground at EGKK I get 24fps for example... Why is my CPU usage so low? Shouldn't the CPU work harder to push out more FPS?

That’s odd cause I can clearly see what the OP is describing.. Having said that I think you explained it well on what is actually happening.

It sounds like you are expecting magic. You are panning the view so fast that features of the VC in the middle foreground are moving across the screen by about 45cm in less than a second. Your frame counter shows you are achieving about 22fps, which means that this distance must be traversed in about 17 frames. Hence on average each frame will be drawn about 3cm to the left or right of the previous one. There is no interpolation, so you're going to see a strobe effect, which I assume this is what you are calling 'blurring'. If you were maintaining 60fps your frames would be, on average, 1cm apart and it would look a whole lot smoother. (Incidentally, this is a good counter to the frequent assertion that frame rate is somehow irrelevant.)

I have to admit I did feel I was lied to by some people on the avsim community I will not mention names, but

This is what people said... it's not about fps it's about smoothness. word not allowed I say! You cannot run smooth at 20fps... 

 

So is there anything I could do to improve the strobe effect?
