Fixing Bad FPS

3jfps remains, in my experience, very useful when running under Vulkan.

Brian, I'm curious what exactly 3jfps is good for under Vulkan? Could you share your settings in 3jfps? I'm going to try it.

Thanks.

directX

How  many use direcct x these days, most developers are persuing after vulcan or other APIS, I since all I sue my machine for is literally Xplane and websurfing. it is irrelevant to most, your not seeking to IT specialists here but the avearage Jo, most who wouldnt even know what RAM was, probably think its a sheep. My laptop month ago on Linux Mint, offered me an update, either complete from scratch or there convoluted method, so couldnt be bothered, mind you may do a fresh install onto a ssd. Linux has come a long way since red hat days 22 years ago, as far as installing and updates but still a headache with upgrades, and tha twill always keep them on the back foot.

Windows has a tiny market share these days. so not many (expensive and rubbish not market leading anymore).

The posit behind the Microsoft purchase of Minecraft was to reach a whole generation who had never really heard of them.

If you have 12 threads working hard, windows wont send more than 4 of them to the CPU at any one moment, and utilisation will be about 30%. A multithreaded OS (like Linux and MacOS) will orchestrate the CPU working on all 12 and run ~300% faster.

I really don`t understand what you are talking about. Windows does utilize all cores if it is programmed the right way. Windows had multi-core support at least since Windows NT 3 when Windows 95 was state of the art. Windows does use as many cores as you tell it to do.

Single thread performance of hardware has barely moved in ten years.

Singe Core performance Ryzen 1800X 2017: 58%

Singe Core performance Ryzen 5800X 2020: 100%

The times Intel released 4% more single core performance  per generation is over, we are on double single core performance in 3 years! I You are totally wrong.

Hardware upgrades do little to improve performance, you should know this by now.  If only XP developers could put out some actual patches to fix actual issues.  Hmmm let's see, MSFS 6 huge patches, hotfixes and Japan world update, in about 2.5 months.  USA coming soon.  Just sayin'.

LOL, let`s not forget the fact they messed up more things than they did improve. Purely entertainment this MSFS thing.

And that's why a lot of Linux users are using rolling release distributions like Manjaro. Don't need to upgrade if you're always up to date.

This, otoh, is true - for windows users

Another misleading and overly generalized statement. On my Windows system I saw a major boost in frame rate earlier this year, when I upgraded my GPU from a GTX970 to the current GTX 1660 Ti. Not just with X-Plane but games as well.

Dirk98, no two systems being identical, my settings probably won't suit yours. Suggest you play with 3jfps (you can set up several profiles). You could let me know your system details, if you like. Probably best by PM.

It has support, its just terrible - especially the non server versions, but even then even MS mostly uses Linux in house now because the windows kernel is so bad at thread scheduling.

e.g.

GPU won't help the CPU bottleneck any more than Vulkan could help your GPU bottleneck

I didn`t found an article which shows the benefits of multi-core support in Linux vs Windows doing a quick search. If you have any link it would be nice to show Still I doubt that Linux runs 3x faster than Windows on multi-core.

from the answer in the third article:

Quote

So main differences:

Windows

• Process scheduling using Multilevel feedback queue + Thread scheduling using Multilevel queue. The thread scheduler simply picks the highest priority thread, the process scheduler is smarter and uses feedback queue.

Linux

• Unified process and thread scheduler, configurable, by default uses CFS. The scheduler uses a metric of fairness and uses priority to skew the distribution of CPU to higher priority processes.

windows has ok scheduling between processes, very basic within processes.

hence (when CPU limited)

yields

(I wouldn't even recommend ubuntu here, too much canary, and canonical are not people friendly)

Depends how many cores you have, windows can fall over as soon as 2 threads within process, but 4 generally, if you only have a quad core CPU nix is probably "only" 1.5x->2x faster.... The gap widens when you get onto real hardware.
