Hello All. I've been a longtime guest here to get tips, tricks, etc, but figured I register and see if anyone else has had issues when updating nvidia drivers. I have an ASUS G74SX laptop to run FSX on. I've had it since earlier this year after deciding to get back into flightsimming due to my frequent long hotel stays. I really have only had minor tweaking issues along the way which the search function here usually solved, but a recent nvidia driver update looks to have screwed things up. My video card is a GTX560M and I installed updated drivers earlier this week to 306.97. My previous driver was the 306.23 version.

 

After installing it, my usual bird of choice (PMDG 747-400) was on a flight from KTUL to KJAX and about 10 miles out from the airport, about 80% of my plane suddenly became transparent while in VC mode. Luckily I had autoland engaged and was able to get her down safely. A few flights before this I've had some sudden transparency issues popup while mid-air and thought to myself what have I changed recently that could have caused this?

 

So today I rolled back the nvidia driver to 306.23 and did a 2 hour 'test flight' with no transparency issues at all. Could downloading the new driver have caused this? Is it even worth it in the future to bother with them if I'm satisfied with my current graphics?

 

In addition to the sudden transparency problem, anytime I'd hit ALT+ENTER to make a fuel adjustment or click on whatever menu item, it would then act up when returning to full screen mode going black. I'd try toggling back n forth from full to windowed mode and sometimes this would clear it up, but I'm hoping the driver rollback solved it all as the only issues have been in the last 2-3 days, with none really in the prior 6 months. Strange indeed!

Make sure you have highmemfix=1 in the Graphics section of your FSX.cfg for disappearing aircraft. Check the video card driver forum to get answers to your driver issues. This is the wrong forum to discuss that.

 

Best regards,

Thanks Jim. I added the HIGHMEMFIX=1 line into my .cfg file. Guess I should have split this post up into two different topics/forums. Last night I tried to replicate the weirdness again both with transparency and by switching from full screen to windows mode numerous times during flight and could not make it act up which is good news.

Glad your problem may be fixed. In regards to splitting your post, I just didn't want this topic to get into a video card/driver issue. That is handled very well in the video card forum. Thanks for your cooperation.

 

Best regards,

Jim
