1776: Virtua Fighter 4: Evolution \\ PCSX2 = ZERO added input lag! PS2 goes in the cupboard! ^ _^
My PS2 and its aging laser are in the cupboard now alongside a PSOne, PC Engine Duo, Dreamcast, and NEOGEO CMVS--because the emulator PCSX2 runs Virtua Fighter 4: Evolution with exactly the same input delay as the PS2 itself on my set-up--5 frames--and with far greater screen resolution and convenience. Huzzah! = D
I measured this very crudely by pressing Jacky Bryant's punch button in VF4E on a PS2, and with a rip of the PS2 disc under each of PS2 emulator PCSX2's five renderers on a Windows 11 PC, all recorded in 60 fps cell phone video. After recording, I play the video back frame-by-frame and count the number of frames between the button being fully down, and Jacky's punch starting to animate. You can do this in YouTube by making sure you're getting 60 fps playback, pausing, and, on PC, pressing the "." (period) key to advance the video frame-by-frame.
This comparison is NOT scientific or conclusive and probably won't reflect whatever you get on your own set-up.
My ~4 year old mid-range gaming laptop: a "Sager NP6858CQ 15.6-Inch Thin Bezel FHD 144Hz Gaming Laptop, Intel i7-10750H, GTX 1660Ti 6GB, 16GB RAM, 1TB NVMe SSD" https://www.amazon.com/gp/product/B089KW3Y1R bought in summer 2020, outputting to a 60 Hz 1080p Asus 5ms monitor. Component output via OSSC for the PS2. Hori Real Arcade Pro V 2017 PS3/PS4 arcade stick--through a Brook Super Converter on the PS2.
I ripped the game disc with ImgBurn and compressed the .iso with CHDMAN. I got the PS2 BIOS PCSX2 requires by downloading PS3 firmware from Sony https://www.playstation.com/en-us/support/hardware/ps3/system-software/ , processing it in PCSX3 https://rpcs3.net/ , and extracting the PS2 (and PS1) BIOS from it with PC BIOS Claim Tool - https://archive.org/details/firmware_bios_claim_release1 : Copy the .bat and .ps1 files into the PCSX3 folder and run the .bat--that dumps one ps3_ps1* and a bunch of ps3_ps2* .bin files into the PCSX3 folder; those are PS1 and PS2 BIOS files.
My input delay playlist: https://www.youtube.com/playlist?list=PLZO3OPzPjIzMl-jcYl0YFhwRYTyP5R8M3
0:00 - start
4:21 - PS2 5 frames
13:45 - D3D11 5 frames
15:17 - D3D12 5 frames
17:55 - Vulkan 5 frames
20:23 - OpenGL 5 frames
23:04 - Software 5 frames
25:20 - Vulkan FXAA 5 frames
29:42 - OpenGL FXAA 5 frames
The game had the same input delay on the PS2 and in all five PCSX2 renderers--and turning FXAA on didn't make a difference.
PCSX2's interface is very similar to that of the PS1 emulator duckstation because duckstation's developer, stenzek, has been contributing to PCSX2 since early 2022 or so. Rather curiously though, Vulkan and OpenGL are in the opposite order in the Renderers list in PCSX2. 'p' Also, while D3D11 is the default renderer in duckstation (maybe for compatibility reasons? but it had twice the input lag in my test with Darkstalkers 3 in that emulator; in duckstation, all but the OpenGL renderer had an additional 1 or 2 frames of lag on my set-up), Vulkan is the default in PCSX2. I couldn't see any real difference between the renderers in these tests, so I'm just going to leave PCSX2's renderer set to Default.
I had the Emulation - Optimal Frame Pacing setting checked, and internal resolution set to 4K, while running the game full screen at 1080p, 4:3 aspect ratio.
