RAM ISSUES CAUSING STUTTERS?

KostaThanks for your reply due to the vagaries of time zone distance I've only just seen it. The bulk of opinion coming from Microsoft and many techo experts is that you do need a paging file. That is the people who developed the Windows OS and should be aware on how it allocates and uses physical and virtual memory.I mainly follow Sysinternals guru Mark Russinovich and while he poo poos the calculation that MS gave for calculating the PF but he still insists that you need one. Even with 6GB of RAM it is still advisable and if you set the min at 6GB and the max at 6GB on say a 1TB drive thats only 0.6% of the drive capacity which is nothing.These articles show what I mean:http://blogs.technet...17/3155406.aspx and one refhttp://blogs.technet...21/3092070.aspx and a mentionhttp://blogs.technet...26/3211216.aspxThe paging file does not affect system performance, and I'm not saying that you cannot run Windows without a paging file, its just without one performance can be affected. Now if Win 8 and the widespread use of 16GB of quad core RAM change the way memory is mapped then we may be telling a different story when IB becomes mainstream.This really did develop into a healthy discussion - I applaud everyone who participated.RegardsPeterH

Peter, the least problems are space here.I did listen to that dude, he talks quite some sense there.If I do system managed here, Windows creates 8GB pagefile.I'll just make on the drive where neither Windows or FSX resides, so I guess it can't hurt me or the performance of both.Now just checked my peak: 6.7GB. I guess what W7 creates, 8GB is healthy.

KostaTo be fair now that large amounts of Physical RAM are becoming common place then the tide of opinion seems to favour none or a minimal amount PF set eg 512MB Min and say 2GB Max. Some argue that without a PF it forces Windows to use RAM more efficiently.If you can get away without having a PF then it can be done and I may have been wrong re-performance as it does not appear to be affected either with or without a PF.This is a lovely article: http://www.tweakhoun...ng-without-one/ for the other viewpoint.On reflection, I can see the day coming when the PF is superfluous - I have used Windows to manage mine so I might try 512 MB min and 2GB Max and see what happens and it will have less chance of getting defrgamented at that miniscule size. Oh! The jury is still out wrt having the PF on a SSD or not. Hmmm!Your comments certainly made me think and set me on a track about stutters in FSX - but that's another story.RegardsPeterH

You know, aside all that this or that is better.Look at it from that viewpoint: why would Microsoft put the option to remove the pagefile in the first place, if it was bad? One could argue: so that you can move it on another drive, but if that were the reason, then you would just get an option where to place the pagefile and that's it. Right now, you have all options, and none make any problems.And crashdump? If I ever start getting crashes, I'll enable it, or use the alternative method.EDIT:I just now enabled PF for testing, made a reboot, and tested FSX boot. 6 minutes.Disabled PF, rebooted. FSX load: 2.5 minutes.Now explain me that.I could do the test 2-3 times to confirm, but, needed?FSX boot after the first one is always the same, 45seconds.

Could superfetch have anything to do with it? I'm not saying it is but it can have big effects on FSX launche times.How long did you wait after windows boot before launching FSX both times?Is superfetch even enabled?Kosta, I can't remember your config and I am sitting on a mobile browser so I can't see your sign, but you do not use SSD or do I remember that wrong?

I don't know if Superfetch has anything to do with it. Superfetch is enabled (Services), by default.Each time I waited approximately the same time - I get my desktop, and after HDD stops blinking, I execute.No SSD here, 150GB Vrap. 2600K@5.0, GTX580, 8GB RAM.
