I have never had an OOM before but I have always used a bufferpool setting and a rejectthreshold, but I tried the BP=0 tweak and did find that my sim became much smoother with no artifacts instead of useing a Bufferpool setting but I have now seen a lot of I guess ding sounds at the end of flights advising me of a possible CTD, which has happened that never did before, so my question is, is it possible that BP=0 can cause this issue?

 

Cheers Rod.

I get the FSUIPC 'dings' warning me I'm low on memory (actually VAS) and I have absolutely no tweaks installed in my FSX.cfg. So there is no connection.

 

Best regards,

Mmmm thanks Jim, interesting, it would be nice to know why this has crept in all of a sudden.

 

Cheers Rod.

You will have to check your VAS usage (either via FSUIPC or via Process Explorer) with and without this tweak to be sure.

I would agree with Oliver, check and find out.
 
 
 Obviously, it's not logical to assume that because person "A" gets VAS warnings and doesn't have cfg tweaks, that VAS warnings because of cfg tweaks couldn't therfore occur.

Having said that, I don't know of any issue with BP=0 and VAS warnings, or what mechanism could cause that.

And, if you are not familiar with setting up the FSUIPC, here's a short guide:

 

Monitoring VAS in FSX or P3DV2 – The freeware or registered versions of the FSUIPC utility will allow you to monitor the amount of VAS remaining during a flight session. This might be valuable in troubleshooting Out-of-Memory (OOM’s).

 

Startup FSX/P3D and then enter the Addon Menu and select FSUIPC. Once FSUIPC is open, click on the Logging Tab and enter 024C under Offset and select S32 under Type. Select where you would like to have the usage displayed. The FS Window is for Full Screen sessions. The FS Title Bar is for Windowed Mode. AVSIM recommends you also check the Normal log file as this provides you information on how much VAS you had to start out with and then it logs usage throughout your flight.

 

The VAS usage is displayed in Kilobytes (KB’s). The value represents the amount of VAS left so, the lower the value, the more VAS being depleted. The max amount of VAS allowed in computers with 64 bit Operating Systems is 4GB’s. This is shared with other applications running in the background on your computer. For 32 bit Operating Systems, the max amount of VAS allowed for FSX/P3D is 2GB’s but this can be expanded to 3GB’s with a switch like the /3GB switch.

 

To convert the KB’s to the amount of GB’s, you should use one of the Byte converters on the Internet like the following: http://www.whatsabyte.com/P1/byteconverter.htm. You will never see 4194304 KB’s displayed as this equals 4GB’s. You might see around 3GB’s (3145728) remaining when you first start up FSX/P3D but that would be unusual. Do not be too concerned with the amount of VAS remaining when you first start up.

 

Best regards,

Thanks for that info Jim I'll use that advise and take a look.

 

Cheers Rod.
