Im not sure what happened but since I've clean installed P3Dv3.3 from 3.2 the performance and stutters have been horrible. Constant frame drops regardless of the plane used one sec at (Example 40fps the next at 18fps then back to 40). I've tried a new .cfg, setting frame limits it still has the drops just to lower FPS, and my system is no slouch

I'm assuming you have put your add-ons back on (?), so was it happening with just default P3D?

Also how clean was the install? Did you delete those App Data and Program Data folders?

It was a complete reinstall,due to a clean install of windows. The only thing installed is p3dv3 compatible Orbx stuff and some add on planes. I also have that haze mod installed.

Hmm, I am not sure if a complete deinstallation also gets rid of this nasty shader folder? Did you check this? Might help to delete its contents once.

I've also reinstalled P3D countless amounts of times and did a full clean reinstall of windows 10 recently because of this. And I'm still not 100% happy with the way the latest version of P3D runs. I have to agree the performance seems worse.

 

One thing I find frustrating is that in P3D 2.5 I was running unlimited frames for a nice smooth experience however since version 3+ I'm unable to run unlimited frames because it then pegs my GPU at 100% and stutters/pauses like mad. So I have to live with a locked 30fps which runs ok however you get that annoying stuttering effect when your turning on the ground or banking in the air.

 

P3D was my goto sim, however since dabbling in x-plane I think thats where its at. Its frustrating. I thought maybe the 970 was getting a bit long in the tooth but then saying that the OP is running a 1080.

 

Something definately is not playing nice on my system.

After a few days pf fighting different problems with 3.5, I finally gave up and rolled back to 3.2 and all problems instantly were cured. 

Had the same thing. Unstable FPS, even in rural areas and clearly worse performance overall. 

Went back to 3.2 and haven't bothered to update again. Could be a driver issue, but I don't care enough to chase it down.

It doesn't I think. You have to go manually delete those folders to do a real complete reinstall.

Xplane has replaced FSX and P3Dv3 as my airliner simulator. I get 50-60FPS with the IEGX 737 at a payware airports and its smooth as silk with no OOM's with P3DV3 and the $135 777 I get 25-30......

I'm still flying with P3D v3.2 and see no valid reason to upgrade to v3.3.

I wish I still had 3.2 but I was forced to do a clean install and it whiped out my backup p3dv3.2 installer and LM for some reason doesn't host older files...

First thing I do before installing any new upgrade, is make sure I have a backup of the original install file. 

I watch a few streamers and they too have gone back to 3.2. I don't have p3d yet, but they were getting bad performance and oom in 3.3, downgraded to 3.2 and said they are having smooth flights again! I am worried as I am looking to upgrade soon to p3d when the fsl Airbus comes out... but now, I don't know!

Hopefully the bugs will be worked out by the time I get back from OCS in November

I'm thinking about doing the same thing.  I have OOMd three times  with 3.35 which never happened with 3.2 (similar settings), and I'm experiencing frequent texture blurring and black airport textures over every airport i pass
