Latency regression in v2.0-77 #1239

Open Soreepeong opened 1 week ago

Soreepeong commented 1 week ago

Current Behavior

From v2.0-77, Sonic Boom: Rise of Lyric is late to respond to jump command.

Expected Behavior

In v2.0-75 and before, the game responds immediately to jump command.

Steps to Reproduce

Use 84cad8b280afa9db7637ec1fd125d1b59970b548 or any commit after that, and use Graphic Pack "Uncapped Framerate" with 60fps option.

Reverting that commit in particular from the latest commit (v2.0-86) will make the problem disappear.

System Info (Optional)

OS: Windows 11 22631.3737 GPU: RTX 2070 Super

Emulation Settings (Optional)

Enabled Graphic Packs:

"Uncapped Framerate" (60fps)
"Graphics" (TV resolution=1440p)

Logs (Optional)

No response

Could you try setting "Maximum pre-rendered frames" in the NVIDIA control panel to a lower value for cemu and see if that fixes the issue?

Driver version 555.99 DCH; I'm not seeing that option from Manage 3D settings.

Closest thing is "Virtual Reality pre-rendered frames", which seemingly is 1 by default which is the minimum accepted value.

Aha okay. It's been a while since I've used an NVIDIA card. Although I read somewhere that they renamed it to or replaced it with low latency mode. Try messing with that setting. Also, what VSync setting are you using in Cemu?

Soreepeong commented 1 week ago

Using v2.0-86: Changing "Low Latency Mode" to "Ultra" did not result in any difference.

On RTX 2070 Super, only "Double Buffering" made input latency consistently high, both in 1440p and 900p configuration from Graphic Pack. There were no issues while using "Off" and "Triple Buffering."
On Intel UHD 770, the game played fine in any VSync mode on 900p. It consistently stuttered on 1440p.
- RTX2070S and UHD770 are on the same PC; display is only displayed through RTX2070S.
On Adreno on Snapdragon Elite, the game played fine in any VSync mode in 900p. It played smoothly on 1440p, but input latency kept increasing as time went, seemingly without upper limits.
- Using v2.0-75 does not change this.

this is the same commit that reintroduced the flashing equipment subscreen in BOTW when using doublebuffering.
