:Raised Eyebrow: Hi GuysI have recently upgraded my computer swapping an ATI 5850 for the new Nvidia GTX570. I ran the driver sweeper and installed the new 263.09 drivers.I then set up the Nvidia Inspector as per NickN's suggestions exactly. I am running an i5 O'c to 4.0Ghz and have 8GB of GSkill Ram.I started playing FSX and all was fine till I started to see these problems.http://picasaweb.google.com/hamishdd/FSXGTX570Anomolies?authkey=Gv1sRgCNiBz4bmvafVWw&feat=directlinkI started to immediately think that I had a faulty card so started to run some stability tests on my card. Knowing that Call of Duty is graphic intensive I played for 45 mins straight without a hitch. I opened Nvidia Inspector and kept a look at the temps and COD it ran about 78 degrees..I loaded up FSX and at first watched the load and temps which never went higher than around 62 degrees. I noticed that these weird flashes were mostly starting when I had the autogen setting on dense or extremely dense. I did a test where I put all the sliders down to the bare minimum bar the autogen one and I still had the problem. I decided to move my cfg file and let FSX build a completely vanilla version but again this has made no difference. I do not have a bufferpools tweak either... It seems that flying anywhere near trees causes the instability..Unfortunately there is only one driver available for this card so I am not sure if I could try an older version just in case its driver related... I am using GeForce 263.09 WHQL.If anybody else has had these autogen spikes I could sure do with some help.....Many ThanksH.

Operating system is...?

SorryOperating System is Windows XP Professional 64 bit.H.

Running FSX in "unlimited", and external limiter locked at 30, fixed my spikinng on 3 computers.Dave

You can try rebuilding your shader cache also.jja

I would be uncomfortable with those temperatures. have you thought of replacing the stock fan, I have a gts 520 and it made a world of difference(mostly bad company 2) even with fsx.

I had a post saying that NickN had come across this and it looks like new Nvidia cards and the latest drivers do not work with Win XP 64 bit...http://www.simforums.com/forums/nvidia-26063-drivers-and-gtx-480-xp-64bit-fsx_topic36533_post214120.html?KW=GTX+480+Windows+XP#214120This is quite a shock... looks like my problem.. tried the external limiter set to 30fps etc but to no avail.I am wondering if I can try and use an older driver even though its not meant to be used with my card... could I do any harm in trying? :Shocked:http://forum.avsim.net/topic/283464-windows-xp-x64-gtx-480-and-fsx-not-a-good-marriage/Should have done my homework..... looks like it may have to be Windows 7 in the end......H. :Cry:

The 400 and 500 series Nvidia won't work with XP 64...at least not yet.I was forced to go to W7 also.K
