Hi,All of a sudden out of the blue this started happening. When I start up the PMDG MD11 or NGX it usually takes me about 45 minutes of cockpit prep and taxi to get out to the runway where performance seems fine. I have a good computer and frames are allways at the max externally locked 30fps. However just after takeoff in either aircraft the FPS will all of a sudden crash to sometimes as low as 1fps, rendering unflyable. I am running in full screen and when I alt/enter to windowed and back again to full screen my fps is back up to the max locked and stays that way for the rest of the flight. When this started happening it was ocasional and severe and now it is just after every takeoff and more moderate like 5-8 fps instead of 1. The alt/enter to windowed and back again allways takes care of the problem. I fly with lots of FTX in Australia but this also happened after takeoff from Nukalofa, Tonga I think I have the aerosoft stuff for that airport. So it does not seem to be the scenery and it happens in both the MD11 and NGX. I hate this stuff that just starts to happen out of the blue. It is this months monthly ghost in the machine. Can anyone help with this?Thanks allot in advance.BTW. It is not my virus scanner, I have Nod32 and have troubleshot this with it disabled and FSX set to exclude. I highly doubt it is windows backround stuff because of the reliable nature of the problem, in other words it allways happens right after takeoff.

Could be overheating Marc, but I would first suggest try using a different videocard driver and see if that cures it.I think the usepools=0 setting would also be of benefit (though not a cure to your specific issue).IAN

As Ian said Marc, but also check your vid card fans are not clogged with dust, give them a good blow out, making sure ventilation is good. Do the CPU at the same time. Also check the fans are not stuck at 40% rpm, use MSI afterburner to force good constant fan speed.Try the very stable 275.33 driver to see if that helps. The NV insp limiter can be used by editing the CustomSettingNames_en-EN.xml like this:<?xml version="1.0" encoding="utf-16"?><CustomSettingNames> <ShowCustomizedSettingNamesOnly>false</ShowCustomizedSettingNamesOnly> <Settings> <CustomSetting> <UserfriendlyName>Frame Rate Limiter</UserfriendlyName> <HexSettingID>0x10834FEE</HexSettingID> <MinRequiredDriverVersion>275.33</MinRequiredDriverVersion> <Description />
