Thanks, hopefully the firmware updates makes this range usable.
I am awaiting this too!
I'll report my findings once I've got a sample working with a 60Hz-compatible firmware.
For those who can't wait; the important deets which I obviously will write in my obvious "60fps Pulsar" tests article on main blurbusters website. I've told NVIDIA I will wait for the firmware before I publish my special edition piece. I don't compete with monitor reviewers who use my display-testing inventions but it is worthy of a special edition piece (like GSYNC101 but smaller).
- Pulsar is best bar none for VRR-Strobe. VRR-strobe crosstalk lower than any VRR-strobe competition (ELMB Sync, AIM Stabilizer Sync).
- Pulsar is to 25% frametime pulsewidth. (Same as "Lightboost 100%" and default ULMB which is about 25% pulsewidth)
- You can't adjust pulsewidth. So you can't get PureXP-like or LightBoost10%-like pulsewidths. No plan for firmware upgrade.
- It will begin to double strobe at below min-Hz. The purpose is anti-flicker mitigation to prevent accidentally searing eyes.
- You have VRR-strobe stiction at the bottom 15fps of range. A frametime spike will turn off Pulsar strobe until 15fps-above min strobe. This is a flicker-mitigation filter, but will affect anytime you want to do a frame rate cap too close to the bottom-end of your single-strobed-VRR range.
- Firmware upgrade coming for 60Hz single-strobe capability.
I have sent a suggestion to NVIDIA to ask them to make the stiction effect adjustable, so that frame rate caps are reliable near bottom-end of VRR range. As it stands now:
- Someone sets Pulsar min-Hz to 75Hz
- Someone caps a game to 80fps
- If there's a frametime spike, Pulsar goes into emergency flicker-mitigation mode and double-strobes.
- It stays stuck double-strobing until 75fps + 15fps = ~00fps
- Therefore, you're stuck at doublestrobe at 80fps thereafter.
The suggestion I sent to NVIDIA is to have a Pulsar menu toggle:
Code: Select all
MENU [Optimize Anti Flicker Recovery]:
- "High Framerates/Normal Recovery (Recommended)" (15fps stiction)
- "Low Framerates/Fast Recovery (Capped Content)" (2fps stiction)
- "Custom" (let user adjust a fps margin slider)
Hopefully NVIDIA heeds my suggestion; because I admonished the large number of capped 60fps use cases.
Guesstimate this will be a February piece, but wouldn't be surprised if the piece slides to March. Everybody knows Blur Busters famously runs on Valve time. That's cuz I can only do so many blur busting battles simultaneously such as CRT simulator or TestUFO 3.0 and other initiatives. Cheers!
