I’ve been doing a lot of “work” with 5.4 recently, trying to get the best out of my rig.  I have thought about reverting back to 5.3, but the “floating” wheels bug at fsdt airports in 5.3 annoys me (LM’s bug, and not FSDT’s fault). Pretty much all testing I do is in the fslabs airbuses, which may not be as demanding as the Concorde (which I don’t have to compare), but are the most demanding planes I have.  I haven’t gotten 5.4 to where I want it to be from a stutter free standpoint, but I do think I’m getting closer.  
 

Traveling for the next week and then will get back into testing and report back.  There are so many addons, external programs I run in the sim, it takes serious time to figure it all out.

oops, I forgot about that. Good reason not to revert back.

It has very few compatible scenery packages so I’d avoid it. Stick to v5 which is a huge improvement over v3. 64-bit compared to 32-bit with a 4Gb VAS limit. No limit in v5 and I use up to 23Gb with Concorde.

Post your system specs as v5 is more demanding.

@TuFun, the weakest element is the i5 CPU. But it meets the minimum spec of v5.

More benefits than drawbacks.

They’re pretty demanding. But the chap I was helping set his Scenery Objects to zero and the stutters were still evident. Pity you’re restricted from the Concorde forum but if you want to contact him it’s Michele Benedetti. I’m sure he won’t mind and he’ll give you access to the video he made.

It’s a brand new PC. The 5.4 install was clean.

My point (and to be fair this is not a good example because the correct thing to do is so laborious) is that when you are troubleshooting, you have only found the cause when you can make the issue come and go at will, not merely when you make it go away.

It is somewhat laborious to uninstall and reinstall P3D to confirm where the problem lies. We’d already spent a week trying various things. Never easy via forum posts when sitting alongside him would certainly have been quicker. But he’s in Italy and me in England.

He seems very happy with his setup now. I know how he feels having gone through my own long freeze problem within a month after spending a fortune on a new PC two years ago. That problem within v5.4 has never surfaced again in v5.3HF2. I refuse to believe the latest version of v5 was without issue.

I don't know if it matters, but I do have an i9 9900k and an EVGA 3080 Ti in a box, never used.

Use it! 😉 You’ll need a compatible mobo and perhaps suitable RAM too.

BTW- If you don't have a good home for that RTX 3080TI I know a man that may appreciate that card since he is on the hunt for a better GPU. If interested ping @IanHarrison as he was looking for a 12GB card. Just a thought.

I am still running good 'ol P3Dv5.3 HF2 and all is fine. I didn't revert as I never made the move up to v5.4 in the first place as it appeared it was an incremental step up which was not worth my time. I considered v6 but the lack of add-on compatibility put me off.  

I don't see stutters and I am also running AIG OCI with around 100 airlines loaded. Also with the latter I am only using the .BGL-based FPs which is fine for what I need.

A reminder of another problem with v5.4 with many contributions from some of you.

Approaching two years and no problems as described in that long topic.

v5.4 is fine for most but for some it’s caused problems that have only been resolved by reverting to v5.3HF2.

 

Is there a better AV program than Windows Defender that is very, very unobtrusive to programs such as P3d or any other program running?

I am not a big fan of Windows Defender, and I would like to find a good AV program that is one click to turn off and one click to turn back on.  I don't mind having to pay for such an AV program.

I do have Malwarebytes in addition to Windows Defender.  I use Windows 11. Perhaps Malwarebytes is enough.

I’ve no real experience but providing you add exclusions Defender is fine and not intrusive at all.

I used to be skeptical of Windows Defender and advocated for a payware AV and firewall such as Bitdfefender and others, but after a good deal of research I discovered that Windows Defender is actually quite good.  When tested against other payware AVs and firewalls it has scored well.  

If you're also using Malwarebytes real-time monitoring, then you should be just fine.
