Help with Assassin's creed 3. Lag/stutter

jonathan1107 · Jan 11, 2013, 06:03 PM

Hi yall. I have 2x gtx 670 in sli... can't play assassin's creed at all... its crazy

the fps seems to be all over the place... I turned off v-sync... and tried with and without sli... same problem... the fps just jumps all over the place constantly... Any clue what is causing this?

my drivers are up to date. (I'm using evga precsion btw)

OneMoar · Jan 11, 2013, 06:04 PM

is "Adaptive vsync" OFF ? check the NVCp

jonathan1107 · Jan 11, 2013, 06:30 PM

No its off. I found the problem... appearantly its the core affinity. God its incredible how pc gaming is more complex than console gaming...

everytime I install a new game I always have to toy around with the following until I get decent performance:

-vsync (off on forced d3d... etc)
- Resolution (refresh rate)
- Hyperthreading, on vs off
- .ini tweaking...

crazy stuff

so just one question: I got a quad core with hyperthreading, which cores are the virtual ones again? ...

#1, 3, 5, 7 are the virtual cores.. I'm pretty sure. (I don't think Intel has changed the order) If you're just doing mostly gaming on your computer right now, it may be a good idea to turn hyperthreading off in the bios.

I'm wrong 4-7 are virtual cores.

jonathan1107 · Jan 11, 2013, 06:36 PM

well I did pay 300$+ for this CPU and it's hyper threading features... had I bought a 180$ i5 with no ht I might consider this as an option...

Hyper threading does help in quite a few other things I do on my PC... but yeah, I'll try turning it off to see if it solves the problem.

its not really the cpus fault its just that ac3 is a crappy console port

jonathan1107 · Jan 11, 2013, 08:13 PM

yes, assassin's creed games are so fun to play, but so badly optimized indeed.

It's crazy how in console ports... you look one way and you get a perfect 60 fps, and you look the other way, and BaNG! your fps drops by half. and it isn't because of view distance and LODs... it's all because of poor GPU/CPU optimization (threading ant whatnot...)

jonathan1107 · Jan 11, 2013, 08:42 PM

so I tried turning off HT, and it doesn't completly fix the problem... Surprisingly, when I set the priority to "real time" in task manager... it helps quite a lot... now I'm trying to eleminate my stupid frame drops... when looking @ a dense tree line...

*** How can I get the game to always start with the "real time" priority in task manager" ?? ***

lower detail from ultra/v.high to high to see if it helps.

jonathan1107 · Jan 12, 2013, 07:02 AM

I lowered everything, and I do gain a 6fps increase avg... but still get unacceptable FPS drops to 32fps (should never happen ... when considering the fact that I have an i7cpu and 2x gtx 670...)

R3DF13LD · Jan 12, 2013, 07:13 AM

U should get boston fix for that game it will fix the low fps problem...

jonathan1107 · Jan 18, 2013, 04:05 PM

I wanna know "exactly" what he's talkin about

R3DF13LD · Jan 19, 2013, 01:36 PM

jonathan1107 · Jan 21, 2013, 02:52 PM

I typed in the name of the file u linked me in google, and I get non-sense results again...

R3DF13LD · Jan 21, 2013, 02:59 PM

Boston Fix

okidna · Jan 23, 2013, 08:38 AM

Turn off your power saving features, make sure your CPU always running full speed, that's how I deal with stuttering in this game.

When I play this game with AMD Cool n' Quiet enabled, I got stuttering and choppy gameplay.
I can't find the solution, but one day all those stuttering and choppiness gone.
Checking my system and I found that my WCG BOINC client is running on the background (I forgot to turned it off, and this is meaning that 90% of the time my CPU running at full speed).
So I go to BIOS, turned off Cool n' Quiet and no stuttering and choppy gameplay anymore.

Also try to set your Anti-aliasing and AF from NVIDIA Control Panel, also make sure that your settings override any in-game AA and AF settings.

Oh, assuming that you bought your game legally then that "Boston fix" is not what you think it is, trust me, I know

jonathan1107 · Jan 29, 2013, 02:13 PM

yeah, that boston fix sounds like the fishiest of the fishiest things ever lol
