Crashes with 4 or 6 games[Help]

Hi,
Im trying to run 4 or 6 multiboxes at the same time, but so far i got was first town in the game, and before i got there i had many crashes when i clicked on npc's to talk or to enter next instance, like 2 games crashed while trying to talk to npc , and other two while trying to get to the new instance, and another 2 after the others crashed loaded to the next instance.I was trying few tips from this site or wiki, also tried few configurations but with no success. Also got the xml file but privatepaste.com dont work for me, so i uploaded it to random filesharing website. Changed all settings to Minimum but didnt switched off Post procesing and vsync since dont know what it stands for.

My computer has:
Geforce GTX 460 SE [1GB]
AMD athlon II X3 460 [3.40 GHz]
DDR3 1600 mhz 8GB
Windows7 64bit
23" Monitor i run the game at 1920x1080 [if i run 4 games all games run at this resolution]

I would definitely switch off post processing as a first step. It can be very GPU intensive.

Also, if privatepaste is not working, could you use something in English, maybe pastebin.com? Most of the people who are likely to be able to help you are comfortable with that langauge but very few of them speak Polish.

Additionally, you uploaded your ISBoxer configuration. For game crashes we need different information, specifically Diagnostics for Game Crashes, see Diagnostics. Any crash message (if there is one) would also be helpful.

Finally, it may just be that your computer is not capable of running that many instances of the game. Can you run a smaller number without crashes? If so, you'll need to monitor your system for bottlenecks to find out how many is optimal.

Added the files you requested also added two pics with crashes that occur. They occured with 4 clients running. And i turned post processing off.

tried with 2 clients now running, the same crash occurs, i think i had lag with trying dialogs with npc because no crash , but when i entered "terraces" the same crash that i posted screenshot , When i launch a single client without isboxer inner space dont have that crashes a lot, I mean that on end game play (maps) sometimes when i try to enter instances i got some similar crashes but i think its because that it is open beta.

Those crashes appear to be because the game cannot find certain files, which is nothing to do with ISBoxer. The fact that you are getting similar crashes without ISBoxer make me even more confident.

A quick google suggests this and that this is a known issue with PoE.

Thx for help, but your links didnt helped , so im still trying and if i get a solution i post it here maybe someone has the same problem.

Ok so they might be a solution but i dont know how to test it:
Heere is the problem to my Path of Exile Shorcut on my desktop i have to add "--nosound" , and with this i got ofcours no sound but my problems should stop. When i run launcher by myself this nosound works, but when i use innerspace this dont work. I added a game with this desktop shortcut(and this shorctcut is ofcours client.exe in main folder which I add in innerspace , but i cant add "--nosound" in main folder of the game only at desktop shortcut dont know why). So how i can make my innerspace to open game through this shortcut from my desktop or how i can add"--nosound" to client.exe. This might be hard to undorstand but see this topic http://www.pathofexile.com/forum/view-thread/51323/page/1 and the first screen you have is with "--sofwareaudio" i do the same with "--nosound" .
Ill wait a moment maybe someone can help. But then i try to reinstal ISboxer.

When you add a game to Inner Space, you would add '--nosound' as a parameter. You can add these parameters to your existing game profiles by adding a "main executable parameter":

Ohhh thank , that would be alot easier than what i did.

I turned off my sound card which was causing the problems, and now everything works fine ^^.

Know its a noob question but how you switch off post processing, where abouts is it. Thanks
