Your CPU time didn’t change between settings so it’s likely what ever is bottle necking is bottle necking on a single core or thread and holding everything up. Whatever hang up, object LOD or process that’s doing that doesn’t change between ultra/low end, so it could be the aircraft, a MOD, maybe the airport or the terrain LOD. These are guesses but historically it’s quite common for something in MSFS to snag the CPU cycle and plummet FPS. It’s usually a mod, setting, app, something like that.

Anyone have a good guess on what the July surprise is going to be? Likely: Some famous flyer related to 4th of July. Hopeful: A new terrain rendering engine.

Increasing sim rate works great in any WT aircraft. I use 4x all the time with the CJ4 and Longitude even in VR. I am sure you could get away with 8x, just don’t let it try and do a 90 degree turn. I flew from the bay area to Hawaii the other day. 6.5 hour flight in RT but I did it smoothly in my usual 2 hour block.

I think the reasoning behind empty your community folder comes from the chance that an add on can cause a performance issue. People leave items in there and swear they can have nothing to do with stutters and performance changes right after a sim update. Then the Asobo broke the sim, look at my FPS it’s now 10 FPS posts start littering the forums. No community item that I am aware of will straight up break the sim and cause full reinstall, but there are plenty of examples of add ons causing performance issues after updates. World Updates are a little different but someone probably has some half baked Hawaii mesh installed and will complain that WU ruined the Hawaii coast or something. I think the message should be after an update empty your community folder first and test if you have performance issues.

It’s my understanding that frame generation does not work well without a Gsync monitor. I personally couldn’t get good results, but I haven’t tried since December. Lots of tearing, artifacts and stutters. Once I got it set up on my widescreen Gsync monitor I was impressed. Again, don’t know if some work arounds since then have been found.

I am trying to work though this and I promise I am searching as much as I feasibly can to find answers. I know this isn't the "traditional" way, but I am also trying to learn through experimentation, so apologies if these questions are misguided. With the Kodiak 100 the BVar for the throttle is ENGINE_Throttle_1_Set. If I create a script and run such as 0.9 (>B:ENGINE_Throttle_1_Set) it will set the throttle to exactly 90%. I don't know how to translate this to an axis that passes values from 0 to 1.00 and all the percentages in between. If I scale the axis from 0 to 1 and use the script as the variable nothing happens. Also, on my Bravo Throttle I have the mixture axis set with ranges for Low and High. They are specific values so once it cross the blue arrow it triggers the event and moves the lever. The problem is the axis constantly resets to the middle. When I load Axis and Ohs the axis is always at 50% even if the throttle is at 0. It also seems to reset once I trigger the "reverser" which is a button press. When I pull the lever all the way back and activate that button, Axis and Ohs is back to showing the black bar right in the middle. Thanks for the help.

Thanks I assumed it was simple. I don't know what I was doing that I didn't see the categories.

I am not sure what I am doing wrong. I have imported a set of scripts and I have also made a few of my own. When I select the Key Down Event and it sends me to the Select Simulator Event there is no heading for Scripts and when I do a search none of my named scripts are available. How do I assign a script to a button? The documentation shows that there should be a Scripts tree item but it's not appearing for me. Thanks.

It’s doubtful. The heavy weather, TAA 4k and ultra settings aren’t the issue though. That the 4090 can destroy. And flying even 1,000 feet over KLAX you can maintain it just fine in the Fenix. The AI and MSFS TLOD being an unmitigated performance dumpster fire are the big hold outs. No amount of power will get us over 60 FPS until that is sorted. That being said the frame generation maintains over 60 FPS.

I picked one up at Microcenter this morning and got some time at end of day to upgrade. Also have a 4090. At iniscene KLAX with the Fenix. Ultra 200/200 3840x1600 live weather I got right at 60 FPS on the ground and it shot up to 75-80 in the air pretty fast. That’s only about 8 or 9 framers better than the 5800x3D on the ground at least. I did frame generation at KAPA with C152 on the same settings and I was 180 FPS with no VSYNC. Crazy numbers. Anyway, I turned off 8 cores and performance didn’t change. The 7800x3D is going to be by far the winner here I think. Would not recommend spending $799 on this unless you render things for work and also flight sim. My guess is that turning off one CCD will be the long run winner even for the 7950x3D.

We can infer with some reasonable logic. If the FPS went from 108 to 80 and all you did was up the resolution that would mean the GPU became the bottleneck. 1080p is the only way a general market tester can put a game in a CPU bound situation. The big reviewers need a metric that is consistent across all platforms. Trying to find the nuances of every game that limit it to a CPU scenario isn't realistic. We all know that you can load up the default C152 somewhere in Utah with TLOD of even 200 and watch the FPS fly off the screen. If you have a 4090 usually the FPS max out because of the CPU somewhere in the 80-90 range. Load up the Fenix with a 13900k or 5800x3D and a 30 series or 40 series and you tend to be CPU limited at 44-52 FPS, add in traffic and lose 8-10 depending on where you are. What we do know is the CPU is the major bottleneck when we start adding in all the things that people on these boards like to add in.

Waiting? The Varjo Aero is beyond decent. It already brings the 4090 to it's knees. It's got the highest resolution on the market. The Pimax Crystal will potentially match the resolution but you have all the downsides of Pimax where as the Varjo has a full year of teething. Crystal will have no FOV improvements. The Pimax 12k is generally accepted as not coming anytime soon. However, since Pimax Crystal is more or less equal specs, waiting for the reviews before deciding is probably smart.

Yeah, it should be noted how frustrating it is that the 7950x3D is basically $600+ USD to get acceptable performance during taxi, take off and landing. Granted those are the most important and exciting parts of flight sim for a lot of us, but really? It's been 20 years and that hasn't' been sorted. I think this will help in VR with Motion Reprojection. In the end if you can get away from being CPU limited which is hard with AI and airports the sim is smooth at 40 FPS, but no matter the processor it seems the CPU spikes are the limiting factor. Not sure how much this will help even with 40% more horsepower. I don't see it not stuttering when crossing that threshold of 1000 feet AGL into a large airport. But, I do think it will be unequivocally the fastest processor for MSFS, I just think the limitations of the game are the problem at this point.

I think the question is whether this reviewer actually got themselves into a CPU bound situation at 4k. Something everyday flight simmers do quite a bit with our Fenix, add-on airports, TLODs over 200, and landing at iniscene airports like KLAX. The problems of giant fluctuations will remain. If you aren't pushing TLOD and AI limits the sim does well and you don't need the latest tech, but I don't know anyone who is sitting at KLGA in the FENIX and getting 88 FPS with AI Traffic.

First reviews are out and it looks like MSFS is once again more cache hungry than Mhz hungry. It seems a lot of reviewers are starting neglect MSFS as a benchmark game but Eurogamer.net and TomsHardware whose previous results seem to be most in line with what people were seeing in real everyday MSFS use have tested again. https://www.eurogamer.net/digitalfoundry-2023-amd-ryzen-9-7950x3d-review?page=2 They took some of their old reviews offline and rightfully so because they were using test results over a year old and the sim performance has changed since then. Although, CPU usage is arguably unimproved. Either way, they mention that MSFS got 99 FPS in their TBM flight over London and for reference the 13900K got 72. That's a 38% performance increase, which is insane. https://www.tomshardware.com/reviews/amd-ryzen-9-7950x3d-cpu-review/6 Tom's Hardware showed similar results. They describe the result as 'nearly unbelievable'. They saw a 53% increase over the 7950x base and basically the same improvement of 43% over the 13900k at stock. They are showing a 45 FPS improvement over the 13900ks at 6ghz. That's crazy but people with 5800x3D have been posting equal performance with the 13900k in forums, but the MHZ myth of flght sim doesn't die easy. I have no doubt MSFS will still have weird large stutters when approaching airports and TLOD pop in isn't going anywhere, but once again AMD and it's cache is proving to be king.
