LAGS when autosaves...! Please help.

[Smoky]

Why is it lagging when it is auto-saving? Im streaming...and its a bit annoying...to viewers...does it really need an SSD to avoid those auto-save lags? OMG

[Smoky]

Actually it is a bit annoying...because im streaming and it lags when it saves...anyone else facing this 1 sec lag?

[Smoky]

Please help anyone??

I have the same issue as well. Everytime it autosaves it stutters for half a sec. That's really the only time I have stuttering besides the occasional hiccup while gliding. Doesn't bother me that much but it is annoying, I'll grant you. I have a mechanical HD as well, maybe its specific to that. Hopefully they fix it with the "final" patch. Just know that you're not alone.

Thanks buddy...thats why i love Pc Community! I really aprecciate it...i feel how you feel i see what you see.! P.s will there be another patch? They said anything? And yea everything is fine with the game...only that half-sec stutter at auto-saves...

Sure, no problem man :). Yeah, there is supposedly going to be a final update. This most recent "interim" patch (as they call it) was just to fix most of the graphical and performance issues (although that is disputed by many). The final patch is supposed to fix SLI issues and other little bugs plus the DLC I believe. I guess we'll hopefully see next month or so.

lags when saving, while streaming...
short answer, your hard drive simply isn't fast enough to do ALL of that at once.
upgrade it to the fastest SSD your motherboard can handle and/or, offload some work to an additional drive, while also making sure you have sufficent ram to handle all that data swapping.

You can avoid this sort of problem potentially by installing the game on a different drive than your user's documents directory. An SSD might fix it, but I really don't know how large those files are. It might not be a throughput issue at all.

LOL i have Average 180MB/s speeds. Even when im not streaming and just playing the game it lags when it saves...so i think its not my HDD :) I recently bought it.Its good enough...i dont have this problem with any other games.

That's sustained transfer rate, I assume. Random access is much slower and keeps the game from running into severe pacing issues where it fills VRAM entirely in a matter of seconds and then spends an eternity figuring out how to deal with the problem it just created :P

Saving is synchronous, usually; the game is not allowed to do anything in the thread that started a save until it is finished writing. That will bottleneck your system. Texture streaming is asynchronous, it happens in the background and the game keeps chugging along if a texture is not finished loading yet.

Bottom line, if you have a faster storage device available, make sure your documents directory is on it. If you have a slower drive, that's where you should install Arkham Knight unless you have a crapton of VRAM.

Why to install my game on a slower drive? :P i didnt understand

[Kaldaien]

Because once you fill up VRAM, the game starts hitching uncontrollably. The faster your drive is, the more often this problem happens. It doesn't remove stuff from VRAM fast enough to keep the problem from happening again a few seconds later. So it's a never-ending cycle of really, really bad performance.

first time im hearing this :) Ok thanks ill try :)

Yeah, this problem has been known since launch. I wrote a tool that fixes this problem as best I could. To finally fix the problem, Rocksteady has to step-in.

I did install to a slower driver 60MB/s but it made it worse...now it lags 1+ secs....and i have some random lags in game too...

[Kaldaien]

You've already got a drive slow enough, there's no reason to slow it down beyond that. The situation I was talking about earlier was if you had an SSD and HDD. The game was optimized for the hard drive in the Xbox One and PS4 (they have the same exact hard drive), you get the best results if you have something that performs about the same as it =P

You were kind of in the sweet spot for texture streaming already. I have a drive that can do 500 MiB/sec sustained and I cannot play the game installed on that drive. It hitches constantly once VRAM fills up.
