EmuCR:PS2 emulatorPCSX2 SVN r4866 is released. PCSX2 is an open source PlayStation 2 (PS2) emulator for the Microsoft Windows and Linux operating systems. With the most recent versions, many PS2 games are playable (although speed limitations have made play-to-completion tests for many games impractical), and several games are claimed to have full functionality.

PCSX2 SVN Changelog:
r4864
spu2x: linux compilation fix.
r4865
pcsx2: Implemented Threaded VU1 :D

Threading VU1 took a lot of rewrites and new code to make possible (MTGS, microVU, gifUnit...), but we finally got to the point where it was feasible, and now we've done it! (so now everyone can stop complaining that pcsx2 only takes advantages of 2 cores :p).

The speedups in the games that benefit from it are great if you have a cpu with 3+ cores (generally a 10~45% speedup), however games that are GS limited can be a slowdown (especially on dual core cpu's).

The option can be found in the speedhacks section as "MTVU (Multi-Threaded microVU1)". And when enabled it should should show the VU thread-time percentage on the title bar window (Like we currently do for EE/GS/UI threads).

It is listed as a speedhack because in order for threading VU1 to have been a speedup, we need to assume that games will not send gif packets containing Signal/Finish/Label commands from path 1 (vu1's xgkick). The good news is very-few games ever do this, so the compatibility of MTVU is very high (a game that does do this will likely hang).

Note: vs2010 builds and Linux builds need to be updated to include "MTVU.h" and "MTVU.cpp".

  7. Impressive. Massive speed up in a lot of games, just tested with Tale Of the Abyss and it works even better than on a real PS2.
    Definitely an important milestone in PCSX2 development history.

  11. WOOOHOOOO i freakin love my i7 930@ 4.05ghz. finally i can run any games that mightve run slow at FULL SPEED. =D, thank you pcsx2 team!!!

    ReplyDelete
  12. Is it real to run games at full speed in intel core 2 duo 2,1 Ghz?

    ReplyDelete
  13. >apparently the speedup is only for intel cpu's

    you are right, because the new MTGS (metal gear solid) code is too awesome for AMD cpus to handle.

    you can also have a good speedup if you delete system32.dll. it`s a virus from microsoft that makes your pc slower.

  14. anyone who bought an amd of all things to play emulated games in the first place is a stupid idiot! Amd sucks balls, intel all day everyday!

  19. Err in have an intel core Quad 2.4Ghz, and im enabled the opcion of the 3+cores but the speed dont Change!! Kingdom Hearts 2 and Bleach Battlers 2nd dont work whit this!! That opcion make these two Games run a litte Slower!!! Why that Happen?

    ReplyDelete
  20. If you pay close attention to the changelog:

    "The speedups in the games that benefit from it are great"

    So, I guess you just found out that these games simply don't benefit from it.

    ReplyDelete
  21. But how i can Know What games can run perfec whit the +3core speedhack? Hmm For those that did work! please tell me the Games that your tested and works!and also in tried the Dragon ball budokai 3(not tenkaichi)Jap! and dint work to!

    ReplyDelete
  41. my phenom has 4ghz until i get my water cooling next week :)

    ^^^^

    lolz, you put a post about how your amd can rape an intel processor, and you need water cooling just to get passed 4ghz? fail LMAO. my i7 2600k can do 4.4ghz on air alone.

    ReplyDelete
  42. oh and i dont stress the shit out of my cpu like some people do, i go stable stable prime 95 for 6 hours plus. Stress is when the water cooling comes in so your 400 mhz difference is not impressive just saying.

    ReplyDelete
  43. what? this only works for intel cpu's? fuck this!

    ReplyDelete
  44. can someone pls confirm if this works for amd also..tnx

    You get what you pay for.

    ReplyDelete
  48. Very good on AMD AthlonII 635!!!

    ReplyDelete
  49. "not 5+ghz on air lol fuckstick"



    biggest load of shit ive ever seen. lol your just saying 5ghz now out of the blue to feel special. there's no proof to support your supposed claim of 5+ghz on air. unless you live in the fucking north pole, that shit is impossible. your just another bitch liar on the internet who cant handle simple FACTS!

    ReplyDelete
  50. Firstly HUGE GRATZ on the effort and progress the devs are making. Second gratz to all you lucky people that can utilize it with their CPU's. Third @ dude with i7 2600k... Please can you tell me price of your CPU and your MoBo. I'm pretty sure Christophers combo is probably twice cheaper. Henceforth the "watercooling" doesn't count as he can buy decent GPU to make up for the price or just best watercooling there is (lame example) and it's not that much "slower" concerning that it's a lot cheaper. You know that there's a world outside of emulation. So, actually Intel can suck my balls.

    @ some idiots. IT DOES WORK ON AMD'S you retards. :p

    @ Christopher

    I think I've found my next CPU upgrade. It's damn right cheap.

    ReplyDelete
  51. Im a liar? okay buddy, go look up on some forums and im not talking about a stock piece of shit heatsink im talking about a copper heatsink with 2 92mm fans cooling it off so check your facts before you talk shit. i can acheive 5ghz (ON AIR) its just not stable.

    ReplyDelete
  52. bam!!!! pcsx2 rules....... i played nd raped time crisis : crisis zone in less than thirty minutes

    ReplyDelete
  53. @Christopher lol look at you, your a fucking groupie, "exactly goran thanks man". you want to suck his dick too? you can't back your own facts up so you get someone else to fuck you in the ass and post it for you. just a bunch of loser amd fanboys who can't face reality, sad really.

    ReplyDelete
  54. @#58 LOL you guys may be having a pointless flamewar, but i agree with you. the guy who is talking about the 5ghz on air is pretty retarded. if its not "stable" at 5ghz, then it doesn't count towards your argument. gotta hate losers online who think they know everything about computers, it's embarrasing to us real hardware geeks. anyways opinions aside, this emulator is awsome! =D

    ReplyDelete
  55. Yea i love pulling shit out of my ass and lie to people on forums because im cool like that? uhh no what gain do i have lieing? How can you tell me what i can and cannot do with my cpu like what the fuck...? Im done with this you people are so immature.

    ReplyDelete
  56. ToL went up from ~20 fps to smooth 60 on my hexacore :3

    ReplyDelete
  57. more speed more 2ghz + core plsssss . not fair for us who uses 2ghz + core. this option is for 3ghz +core and for 4ghz +core. you forgotten the 2ghz+ core. thats not fair. we cant afford money to buy a new pc. cmon more speed begging here.

    ReplyDelete
  58. excuse me, im not sure but, can i safely use that hack w/ only 2 cores?
