As you will find out below, final burn alpha has 2 more frames of input lag when playing offline on a lagless CRT.
2/60 = you are deprived of 3.33% of a second to react to any moves.
With turbo speed set to turbo 1, the game is 2.67% slower overall. But it still does not feel as responsive as arcade.
With turbo speed set to turbo 0, the game is 4.95% slower overall, you have enough time to react but your input will still come out slower.
And that was for offline with lagless CRT. Most LCD has lag. Also when online lag comes into play, you can see that playing at a slower turbo setting will be better.
Crouching Round House Lag test (aka NKI Test)
CRT setup is tested at 800x600 resolution
2.4Ghz core2duo laptop has a builtin onboard intel mobile 4 series express graphics
macbook air is 2012 model with i5 process and HD4000 graphics. lcd at 1440 x 900 native resolution
pretty cool. Have you tried this on different machines? because I’ve heard the main problem with PC emulators is consistency in speed/lag etc… because hardware is inconsistent. That’s why my preferred offline alternatives are console solutions. Dreamcast / Console MAME.
but really I just lug around my arcade board and supergun :lol:
I would do speed comparisons myself, but I don’t have the equipment/knowledge to accurately time my arcade board vs PC on mame.
If the performance is as good as you say then it’s a very nice resource to have. Eventually, arcades will be less and less accessible to everyone and the game will survive if we have a setup that is the same for both training and tournament environments. Fingers crossed.
Yes, it is assumed that your pc is reasonably powerful.
I forget to mention that I was using a i5 2500k with radeon 6800, which is overkilled for emulating cps2.
I tried the same test on a core2duo 2.4ghz laptop with a mobile 4 series express chip vga, the game play speed is the same.
Game play is 99% ok except when there are fireball slowdown + super, the vga is not fast enough to handle it.
Running it on macbook with 3rd gen i5 hd 4000 graphics it is as smooth as running it on my desktop even in tense situations.
I have no access to a 2nd gen i process with HD 3000 graphics but I assume that would also be sufficient.
Just make sure you have a clean windows installation and no malware adware antivirus heavy duty processes running in the background.
supergun and arcade board are easy. The problems are CRT and custom input. The latter can be solved with undamned’s cps2 but CRT will still be a big problem going forward.
Speed comparison is easy. Just recording the same stage on the same turbo speed and transfer the video to your PC (ideally 60 fps but 30 fps is ok).
Use media player classic Ctrl-G to jump to when “Fight” appears on the screen.
Mark down the seconds to the decimal place and do the same for “Time Over”. Subtract and you got the numbers.
The 2nd test I did was crappy core2duo laptop with mobile 4 series express graphics output to CRT at 800x600 resolution. using shmupmame with 99% speed setting (everything else is stock) on windows 7 with aero disabled and mame running at full screen.
The crouching RH also comes out majority of the time at 4 frames, with a few 5.
I would say the average number is 4.3
soooo for us less informed, why would you use this particular emulator over regular mame? you can adjust the emulation speed in it too, in fact in the slider controls the main cpu is already at 74% by default, the significance of which i don’t know but if i crank it up to 100% the game speeds up quite a bit.
This version of MAME was designed by the shmup community for the sole purpose of reducing input delay. So for all intents and purposes, their version of mame works perfectly with what fighting game enthusiasts look for in an emulator as well.
Man, I headed down this path a little while back. Its not difficult to do, from a building perspective…BUT its difficult to locate a modern motherboard that has a ps/2 port that isn’t tied to its USB controller.
