Well, it does strobe @ 240 hz. Strange thing is, i'ts also really smooth under 240 fps, or even 400 fps.
From what i remember basically anything not being exactly 240 fps , (or 120 fps in those days) was an absolute crap fest when strobing.
It seems that that is no longer the case, i don't understand HOW though. I checked multiple times if the strobe was really on, and it is .
Am i the victim of wishful thinking/placebo effect ?
I think i'm just going to leave it on always.
What do You mean?
Normally, with typical ulmb, if You drop below strobe refresh rate, the gameplay feels kinda juddery and frames are dupplicated.
Is dyac different in any way? I never used ulmb because in games where I could not reach constant 144hz on ag251fg, it felt bad... so I always ended up using gsync
Techno Viking is right to an extent. While it's not as smooth as perfect triple match (framerate = refreshrate = stroberate) of the most perfect possible strobed motion ...
Sometimes it is amoother to do 100fps@240Hz strobed than 100fps@120Hz strobed.
This is because there are less refresh-cycle rounding effects, so the maximum stutter vibration amplitude can be closer to 1/240th the motionspeed, rather than 1/120th the motion speed. From a software developer perspective -- depending on how "gametime" is calculated (e.g. gametime derived from refresh cycle times, or gametime derived from actual microsecond timestamps), your stutter amplitude may be halved at 100fps@240Hz versus 100fps@120Hz.
Yes -- you do have more multi-image effects at 100fps@240Hz than 100fps@120Hz, but some people are more bothered by the "stutter" than the "multi-image" effect. A smoother multi-image may be preferable to some people than a stutterier single-image.
Motion quality is a complex topic that covers:
- Motion blur
- Multi-image effects
- Refresh rate & frame rate effects can affect all the 3 above very differently
Now, if we're comparing 100fps@120Hz versus 220fps@240Hz (20fps below), you'll definitely have much better strobed motion at 220fps@240Hz than 100fps@120Hz. That is, if your display supports 240Hz strobe modes. If you've bought a 240Hz monitor, you probably have a more powerful GPU than you did when you had a 144Hz monitor. The overkill framerates, the overkill Hertz, all simultaneously help reduce stutters.
Some people are not motion blur sensitive, but are stutter sensitive. Others are multi-image sensitive and motion blur sensitive, but not really stutter sensitive. Some people don't see tearing, others do see it well. Some swear by GSYNC, some swear by ULMB, some swear by neither of the above. Human vision has funny differences in sensitivity between different people.
Obviously, if you're sensitive to ALL the above (blur, sutters, multi-image), you definitely need the triple lock (framerate = refreshrate = stroberate) to make your video games as perfectly TestUFO-smooth or Nintendo Super Mario CRT smooth, with the perfect zero-stutter zero-blur motion. This magical "60fps CRT" effect only occurs on strobed monitors with the triple lock (framerate = refreshrate = stroberate), which means 85fps@85Hz, 100fps@100Hz, or 120fps@120Hz.
However, not everyone needs or wants the triple lock -- and wants the lower input lag of VSYNC ON, but with most of the benefits of blur reduction. Overkill framerates is your friend.
But if you want to temporarily stare at microstutter-free ULMB/strobing/etc.
(bear with the input lag temporarily, this is just a motion demo to copy the "TestUFO smoothness" into your favourite video game)
1. Enable ULMB
2. Enable VSYNC ON
3. Make sure your framerate is maxed out
4. Use keyboard strafe left-right while standing very close to high-detail-texture walls to high-speed pan.
5. Observe the CRT effect (zero-blur zero-stutter effect).
Basically, anything that causes perfect-motion panning. (bypass mouse microstutter error margins). Or try fast keyboard scrolling in RTS scrolling or platformer -- anything that causes a roughly ~1000 pixels/sec panning motion in your game -- or 3rd person view spinning in place -- to create scenery panning speed roughly same speed as a TestUFO UFO at default speed -- to hunt for microstutter visibilities.
Now, 200fps VSYNC OFF at at 240Hz can probably look decently good enough to the average gaming mice, since many gaming mice don't turn left-right as smoothly as keyboard strafe left-right. The mouse microstutter of the average gaming mice (even 1000Hz) can pretty much be worse than the microstutters of 200fps@240Hz VSYNC OFF strobed. So you might not be noticing the microstutter of framerates below refreshrates during your strobed mode. (It is often ultra-tiny microstutters, even single-pixel and two-pixel jumping -- the "jittery stutter" effect of strobing can be MUCH smaller during 240Hz strobing)
If you want a mouse that can turn left/right as smoothly as keyboard strafe left/right, you need a very good gaming mouse & a very good mousepad (not your desk surface). It's very difficult to completely eliminate mouse microstutters to the point where the strobed smoothness of mouse turn left/right is identical to the strobed smoothness of keyboard strafe left/right.
