I know its only a very short flight so what's the best time duration do I need to test vas.

One way is to start sim with no weather engine, nothing running and leave it for a coupe of hours, VAS should remain the same.

 

Am staying with 376.33 as Ive long given up looking at 1GB of VAS left after a flight. Until a driver comes out that give better FPS etc for P3D I don't see the point, if its not broken etc....

The reason I included the pause was I use to get high vas loss during this.

some other stats Fsuipc log file

Minimum frame rate was 16.7 fps, Maximum was 30.7 fps
Minimum available memory recorded was 1429Mb
Average frame rate for running time of 8091 secs = 25.8 fps
Maximum AI traffic for session was 61 aircraft
Traffic deletions 0 aircraft
Memory managed: 4142 Allocs, 4141 Freed

IMHO reverting to an earlier driver is fine given that frickin' nVidia does absolutely NOTHING for us anyhow.

Yep. There is probably little advantage to getting the latest and greatest NVidia drivers, for those whose only installed game is FSX/P3D. We are kind of a forgotten backwater in the gaming world, due to the ancient techniques the sim uses in its video engine. P3D is a bit better in that regard, but only a little.

I used version 362.00 for almost a year on my GTX970. I only recently updated to 376.33, and really see no difference in performance whatsoever.

Win10 users of course, will get the newest drivers whether they want them or not, unless they have locked down their updates to prevent that from happening.

Driver updates would be fine, even if they offer no improvement in a specific game - as long as they don't have the opposite effect, of degraded performance or memory leaks.

I don't  think that it's  so much that, but rather nVidia  issues new drivers to support just released "hot" games and often the new driver breaks things for other 3D apps. For example, the 378.xx series drivers are supposed  to improve CPU threading  for DX12 games, which is nVidia's focus at the moment.

I'm still on 372.70 and it's working great both for P3D as well as other titles.

Personally I think the only reason to upgrade a driver is if you know the new version will solve a specific problem you're suffering from.

The big issue for those of us who play games other than FSX/P3D is that new releases often require the latest driver. We're a tiny fraction of nVidia's base, but it still sucks being left out in the cold.

I've been trying out lots of brand new titles in the Oculus store using 372.70 with no issues but I guess it might be a different story with "normal" titles.

Put on night environment UK. Aerosoft Heathrow,  uk2000 Gatwick,  and orbx England,  set the sim to 2200z and taxi out.  I doubt you'll even make it to the holding point.   This is of course all the ndivia drivers fault.

With UK photoreal + custom AG + AS Heathrow Extended I can not only make it to the rw but also fly over London enjoying the NE nightlighting.

However , I use the Prosim cockpit suite ...

Thanks for your input and suggestion, don't have some of the titles you quoted but do have NE. so installed it and..

at EGLC.. day

vas   357308

at night .. loading stopped at 25%

turned NE slider off and restarted sim  vas 1356324 (day)

I think NE suggest druring off during the day.

I'm currently doing ltn to arn in the oom sim labs 320 and been getting the vas dings all the way down from the TOD.   It's heartbreaking the guy who made the hilter video on YouTube is spot on.

I am using 378.88 with a 1080 on win10 64 bit and I have no vas leaks or excessive vas usage.  And I was using 376.33 and 376.53 prior.  I know I will be getting a lot of questions, so I plan on making a more in-depth thread later this week when I have more time.
