Stutter and lag completely gone Thread - MISERY mod for S.T.A.L.K.E.R.: Call of Pripyat

I know Jasper already start the thread here Moddb.com.

Please read it a bit and test the values within. I have to share this with you guys because I know how annoying these little pesky stutter feels like when we trying to enjoy the game. Jasper did find the key line to eliminate the stuttering and lags, so far my game is running so smooth the stuttering and lags are completely gone. You guys need to try this out and feel it, and please feed back on any major bugs with this tweak.

except that doubtfully will work for us people with pc's of poor video cards such as 550 GTX TI and computers out of this decade... can't imagine myself runnign with a 900 distance. Also the NPC's tend to kill themselves out wayyyy before I get to that place.

But others might benefit who have more modern vid cards and pc's.

I think Japser's 600 may work out well. Mine isn't that high end and still able to handle high distances. The key is Object per update set to 1.

It can't hurt to try. CPU speed is important too, single core speed. Change Objects_per-update to 1, check FPS. Nudge switch_distance 50 at a time until FPS starts to drop off. Even if you don't improve FPS, the smoothness is worth the effort.

I will try to change the Objects_per-update to 1, but I'd like to keep my original distance of 300(or was it 250...?The default one when installing mod). So will this do anything ?
Also you mentioned that for some reason I have to delete my user.ltx file ?

Try just changing it to 1, you have nothing to lose but maybe shorter stutters.

Wish we could have found the value sooner. Stalker feels like a different game now. With super good quality graphic and smooth realistic combat.
Shall we look into modifying the classes? I just found out assault rifles with good scope can actually beat sniper rifle, making assaulter op class.

I've always leaned towards the Sig-550 because it works close and good enough long until you can get something with a really good scope. It's easier to find/fix up early on when all the Sniper rifles fire so slow you can get minced up. Besides, having lots of bullets in the clip and being able to go full auto helps in a pinch ;-) It will greatly benefit those with mid-range multicore cpu's because they can probably run higher switch distances without overclocking. I've benefited from having mine cranked up to 4.5Ghz but it hardly gets warmed up anymore. Did your GPU used to race on the main screens before and then suddenly stop doing it a few driver updates ago? Mine never races anymore so I turned off my frame limier. Newest 344.75 driver works fine too BTW.

By changing the distand to 600/900 from 300 (default), don't you miss any good fights ? I mean, with such distance, everything would happen before you arrive to any place, doesn't it ?

Changing the Objects_per_Update to 1 makes stuttering shorter in duration, every bit of extra switch_distance makes the stutter/lag happen less often. Enemies can't see you past around 250, I think, but you can see them sooner and begin sniping, or evade if that is the correct tactic. I believe the team has optimized things to enable higher switch distances more efficient, but there is a limit to how much your CPU/GPU can process before performance begins to again drop off. The default of 300 was to enable more modest rigs to play the game. The beauty of the zone is new groups are always spawning, so I don't think you will miss much action, you will just have more to choose from at a time. My CPU is running over 4.5 GHZ, and yet DesertEagle5 is getting 900 to work with a lower core CPU speed when I'm managing only 600 before FPS starts to drop a little. He does have a better GPU than me. Everybody will benefit from trying out a few things to find their own sweet spot. It's very easy to adjust and just as easy to switch back. I think some stalkers who didn't think their rigs could handle higher settings are going to be very pleasantly surprised.

Mighty good work Jasper34, and thanks also to DesertEagle5. Zone hero's in my view. After Misery devs of course.

You welcome. I honestly hope everyone can enjoy this. Stalker game without microstuttering is really enjoyable. Great mod can now be enjoyed at full extend.
I am trying to find a sweet spot in switch distance. 900 works but over kill, 600 works just fine. I personally believe each map has different sweet spot for switch distance since they spawns are quite different.

Just had full run in Zaton, everybody still there. Bandits are still annoying as usual. Mercs repopulate correctly, mutants kept on breeding so never run out of targets. Monolith moved in after I cleaned up Water process station for them. Iron forest is full of mercs for some reason, the only locals missing are 2 controllers at saw mill. Guess they need a vacation. Going back tonight for another visit just to make sure everybody is home.

You're right about different switch distances in different maps. I wish some really clever programmer would find a way to make a slider for it in the GUI. I've only had 2 non-repeatable crashes. The second was while 2 Pseudogiants were stomping away nearby while I was heavily engaged in Jupiter.

Haven't had a single crash since the tweak. Everything is normal on all 3 maps, except Pripyat is bit empty for me.

Wait, deserteagle. Do monolith spawn in Zaton at all?? Never seen them there. Is that a after game end type of thing??
Alsow, Iron Forest is a normal place for mercs to hang out. Usually they travel in that area, aswell as the workshoops and gas station and such. The south of Zaton is where all the cool firefights take place. Same for Jupiter aswell actually.

Oh yeah, forgot to mention that I am enjoying playing with a switch distance of 600. The map is alot more dinamic, and Im having huge firefights with multiple targets at the same time. Cant explain how, but it seems that my gunfire atracts way more people now. I once had to kill 5 mercs and 4 bandits in one single spot. The odds werent in my favour.

Monolith appear after you visit Pripyat once. They refill the processing plant in Zaton, the checkpoint and around the Pripyat plant. Adds better level enemy later in game.

Ddddouble entry ... oops.

So I see. Never spent to much time in Zaton after I reached Prypiat. Shame really since Zaton is my favourite map due to the high hostil NPC count. Will definatly hunt down some Monolithians after I reach Prypiat again for sure.

Yes Monolith spawn in Zaton. I believe it is after the quest when X8 Lab is completed. I know after we evicted the mercs in the laptop quest, water process planet usually spawn bandits. (and boy aren't they rich, always carrying a lot of goodies). At some point in the main story line (usually quest for central lab) monolith will move in. They don't patrol the areas like mercs or bandits, so we have to go inside to hand them eviction notice.

I had a lot of fun in Jupiter too, with 600+ distance the map is heavily populated at Factory and check point areas. Saw bunch of cats hunting bandits and I was laughing, except bandits didn't last long and cats are looking at me right after, cutting my laughter short and run for my life.

well so far i'm up to 950 meters alife distance, and it seems like the higher i go the less frequent and shorter the loading stutters.

it's harder to determine framerate, mine seems to tank to 30-40 when i look up close at trees and grass but i'm not sure why yet, i do have antialiasing at 8x and AA transparency at 8x in nvidia control panel, but changing that didn't seem to affect it. otherwise i get pretty much 50-60 fps, quite playable

it seemed like my best framerates were at 600 and 850 settings, but i really like being able to see super far across the map with my sniper scope

If you find a really sweet spot please post your hardware config and details on the Alife Stuttering thread so the team doesn't have to sort through all the boards to find it. I think we may need a different setting on each map due to the high degree of graphical difficulty between maps. No idea yet if that's manageable with resorting to manually editing after changing maps.

Yeah, i'm just playing around with the beginning area. Hell, I've barely played the game at this point.

I just switched GPU's going from an Nvidia to an AMD card. I started out with HDAO, but found noticeably less stutter/lag on HBAO. I'm still using 700 Switch distance in Zaton and 600 in Jupiter with 1 Objects_per_update.

I have set my Alife to 500 in Pripyat, 700 in Zaton and 600 in Jupiter. Only encountered very few stutter in Jupiter. Not sure if it just me but Pripyat felt more empty now.

Pripyat never had much in it except the base spawns. Jupiter was always the most dense. Zaton is so open and mainly empty I think that's why we can run so high there except maybe around the waste processing plant. The flora and buildings are much more complex in Jupiter. Those poor bandits at the checkpoint had Pseudodogs, cats, boars, bloodsuckers and Pseudogiants running around. I almost felt bad shooting them in the back ;-) Then I have to run for a high spot to clear the herds out.
