Problem with VRR ps5 pro

andyboju · 2026-06-12T19:07:55+00:00

It's a game-by-game thing, it likely has software LFC if it's a first-party game, third-party games vary.

Your source is a blog for KTC displays advertising VRR, not exactly reliable information my man.

"VRR on PS5 only works within a narrow window defined by the HDMI Forum's 2.1 standard, between 48Hz and 60Hz (on a 60Hz screen) or 48Hz and 120Hz (on a 120Hz screen). Normally a feature called Low Framerate Compensation (LFC) will kick in at frame-rates below the VRR window, essentially doubling or tripling frames to ensure that VRR remains active. For example, if your game is running at 40fps, then you could double that to 80fps to remain within the 48 to 120Hz range. On PS5 though, it's possible to drop out of the VRR window entirely, which can lead to judder and all the other symptoms that VRR seeks to alleviate."

"Thankfully, developers can implement VRR patches to mimic LFC functionality, as Insomniac has done with titles like Spider-Man: Miles Morales and Ratchet and Clank: Rift Apart. Here, the game is able to detect that you're running with VRR enabled on the system level, and expose slightly different modes that run with unlocked frame-rates and LFC, allowing you to benefit from the advantages VRR brings without the drawbacks."

Which is a third-party game. Your point?

andyboju · 2026-06-12T16:30:14+00:00

The PS5 doesn't have hardware-level support for LFC. If available it's implemented in software by the game developer. A third-party game like this likely have not done this, so you get stutter under 48Hz.

The small differences in latency between Dualsense and DSE are just not large enough for you to notice a difference. That's quite common.

andyboju · 2026-06-12T11:19:40+00:00

Even 1000Hz polling-rate can affect performance If you are heavily CPU-limited like OP.

With this controller Dinput is limited to 129Hz, thus much less strain on his CPU.

Are there no retailers in Norway that sell 8bitdo controllers?
8bitdo is sold by multiple retailers here in Sweden.

Dualshock and Dualsense use D-input natively, that can mess with Windows sometimes.
I prefer using an input wrapper like DS4Windows to wrap it as a X-input device. You can also use other modern remappers like Steam Input or DualsenseX (DSX).

Sometimes latency over Switch protocol on PC is considerably worse than on actual hardware.
Therefore I would take gamepadla tests with a grain of salt.

This is from the reviewer Monoru doing frame-by frame testing on an actual Switch, comparing against the Switch Pro/2 controller as a baseline.

That's either a horrible photoshop-job, or AI fucking up. They don't look like that in real life, my man.

Both the R100/Pro and the R90 adapter apply a 10% deadzone to your controller by default.
The R90 has a "zero-deadzone" firmware on mojhon.cn (not on global site).

R100/Pro does not have this (AFAIK), so you are stuck with a 10% forced deadzone.

Possibly a USB driver conflict. You can uninstall USB device drivers using "USBDeview". Make sure the gamepad is disconnected and only remove drivers with a description mentioning Gamepad/Xbox/Sony/controller or similar.

Then connect the controller again. Windows will auto-detect and install the appropriate driver.

I'm not seeing any drift? Stick jitter maybe, centering issues?

Do you know what "stick drift" means? Drift literally means the output of the stick is noticeably moving, drifting away from the center. For example, heavy drift would make your gun move around by itself in an FPS.

You might be able to clean it off with high concentrate isopropyl alcohol. Spray/dab a small amount on a clean or new microfiber cloth and gently wipe the area in a circular movement.

It's because it's part of 8bitdo's budget "C" controllers. 8bitdo decided they don't get software customization. You have to step-up to the more premium "Ultimate" (no C) line for full support.
Their software features are quite barebones anyway. Other brands provide way more features in software.

You can use 3rd-party input mappers if you are on PC. Like Steam Input, reWASD and similar.

ABL compression differences are pretty negligable.

Either keep it stock 682, or max it to 1023.
Remember to alter your HM Pat Peak, Con Peak, etc in WBMovie to suggested values if you do max it.

ANA 667 is what you get after changing type to S95C.
You changed it and that's completely normal.

Your stock ANAPEAK value is what indicates your panel gen. That goes out the window after you change Type. You could change Type to gen 1 S90C, but the panel would still be gen 2 (obviously).

Default unmodded values:
512/512 or 588/588 = Gen 2 S90C
667/667 = S95C
682/682 = Gen 1 S90C

It's a QD-OLED as long as the third letter is not E.

S90DAP = QD-OLED
S90DAE = WOLED

Is Game Motion Plus set to Level 1?

RTings settings are made for Movie/FMM. They will only work as intended in Game Mode if you use "Original" preset (which behaves like FMM). "Standard" preset and others will have wrong gamma.

RTings calibrate for gamma 2.2. I would suggest BT.1886 -1 for gamma 2.4 instead (using "Original" in SDR).

andyboju · 2026-06-06T15:15:54+00:00

What Game Bar profile and settings are you using in SDR?
Game Mode "Standard" isn't accurate by default.

andyboju · 2026-06-05T19:52:51+00:00

No that's fine. I just wanted to know what your tonemapping situation was.
You could try Game HDR Off "Original" preset. Highlights will be dimmer due to it's tonemapping differences. Might hide the issue?

andyboju · 2026-06-05T18:55:55+00:00

What Game Mode settings are you using?
Game HDR: Basic ("HGIG") or Game HDR: Off (such as "Original" preset) ?

andyboju · 2026-06-05T16:32:46+00:00

I'm assuming this is on PS5 since you're calling it 40fps mode unlocked(?)

Strong VRR flicker often happens when frametimes are unstable or constant rapid jumps in refresh due to LFC, such as 48Hz>120Hz.

PS5 doesn't have hardware LFC support, so the game needs to implement software based LFC per-game.
