VNAV ALT does makes more sense, thx!

I'm curious about what kind of CPU and GPU will run both PSX and MSFS and give good results in demanding scenarios.

I typically run the following (all at once, on the same machine):

- PSX (two instances)
- MSFS 2020
- MSFS_AutoFPS
- RealTraffic
- PSXTraffic with AIG models
- Navigraph Charts
- Spad.next
- Several Chrome browser windows, maybe a YouTube video

My system is this:

- 11th Gen Intel Core i7-11700 @ 2.50 Ghz
- 16 Gb RAM
- NVIDIA GeForce RTX 3060 Ti

I have my frames set at 40 (minimum) in MSFS_AutoFPS, most MSFS settings high but not max (e.g. clouds are high), and I get extremely fluid performance at altitude, on the ground at medium airports, and when the injected traffic in MSFS is around 10. Right now I'm flying from Hanoi (VVNB) to Dhaka (VGHS), two "medium" airports, 4 live aircraft on PSXTraffic, and the FPS in MSFS has been 47-52, really quite good. (PSX is always steady and fluid at 60/3, thank you Hardy.)

But alas, I've never been able to fly into KORD with everything above; it brings my system to its knees, with MSFS's FPS in the teens, too stuttery to be useable. So I'm curious, if I wanted to upgrade someday and fly into KJFK, KORD, or EGLL, what kind of hardware would I need?

Specifically, if you are getting good performance on MSFS 2020/2024 in demanding situations, with PSX running on the same machine, what are your CPU and GPU?

Thanks.

Hi Will.

My 2 cents here after having experimented A LOT with PSX and MSFS2020 and MSFS2024 on same PC during my homecockpit build evolution.

No matter how powerfull PC i used I never ever got a stutterfree experience with FS2020 and PSX coexisting on the same PC. This primarily had to do with FS2020 not being able to really utilize multicore processors fully and any time I started a PSX instance it had direct negative impact on stutters - so much that I completely discarded the idea of having PSX and FS2020 running on the same PC (5950x 16 core with 32GB Ram and RTX3090)

Since then I changed the processor to the 5800X3D which improved stutters a lot in FS2020 but never fully. Now after FS2024 is out it is a completely different story as it can utilize multicore CPU's much much better.

The transition to FS2024 resulted in that I again can have a PSX instance running along on the same PC without any noticeable negative impact on FS2024. I currently us this PSX instance to display the P6 CB panel on a 27' Touchscreen and provide windscreen audio from PSX.

My recommendation is the following:

1: Move to FS2024 if possible for you - I have done it and not looking back as it visually and performance wise smokes FS2020 on the same hardware. See how that performs on your PC before doing anything else.
2: Forget about Intel processors at the moment - go for AMD X3D cpu variants (I am still on the old original 8 core 5800X3D although I am eyeing an 9800X3D system when my local PC pusher will get restocked in January
3: Get 64GB Ram as especially FS2024 is hungry at high settings
4: GPU wise it depends on which resolution you are targeting but you could keep your 3060ti for now and upgrade if funding allows. A 4070 or greater will work magic.

So to answer your last question then I am now running FS2024 coexisting with one PSX client instance (on separate 27'4K monitor) running FS2024 in 4K resolution with GFX settings mainly in ULTRA setting with some settings in HIGH.
I run VATSIM via vPilot, PSXT with Realtraffic injection, PSX.NET.WASM - all on a PC with 5800X3D with 32GB Ram and a RTX3090. I have a smooth experience in EGLL, KJFK, EHAM etc with frames rarely getting under 30 FPS.

Hope it helps.

Cheers

Specifically, if you are getting good performance on MSFS 2020/2024 in demanding situations, with PSX running on the same machine, what are your CPU and GPU?

In some ways the KJFK approach is more difficult.

I am sorry to ask an obtuse question, but why is the KJFK approach more difficult? I do enjoy Canarsie Approach quite a lot (my favorite one for KJFK), but I thought that VHHX was more challenging due to the winds.

I think the main difference is that if you went wide on the CRI ATC would DEFINITELY have something to say!

KJFK ATC always has some comments, sometimes funny (legendary (to some aspect) Kennedy Steve comes to mind), sometimes (most of the time?) very confusing for non-English speakers (using completely non-standard phraseology). Lately, they have been quite strict with read-back and "proper" communication (https://www.youtube.com/watch?v=M9HpMCnSILc)

Cheers,

Hello Hardy and Hoppie,
thanks for your inputs. It is quite intriguing, but makes logical sense.

Thanks!

VNAV ALT. Maybe the instructor refers to a very old FMC version from 1988 or so.

When you don't follow the predicted VNAV path but get caught in level flight at the MCP ALT, the mode changes to VNAV ALT. The long level flight segment after the T/D is not the predicted VNAV path but an MCP ALT capture.

Hangar 7 / VNAV PTH or ALT

Does the FMA say VNAV PTH or ALT when passing T/D (late descent)?

It takes a certain amount of courage for an organization to intentionally deviate from published procedures. Cathay's home base is Hong Kong, so they may have been more at ease with both the actual situation there and the relationship with the HKCAD that allowed them this "deviation". I can imagine that foreign carriers were a lot less inclined to experiment.

I find it hard to believe that an organization would teach an intentional deviation from a published procedure.  If the airline did, I'm not going to ride on them.     

After watching the video the aircraft appeared to be downwind on base and the wind sock showed about a 20 knot crosswind on landing. This could easily push the aircraft wide and lead to a steeper bank on the turn to final.

The IGS13 into Kai Tak is very similar to the RNAV Z RWY13 into KJFK.  In some ways the KJFK approach is more difficult.
