Hello,

 

Won't the screen resolution greatly have a large impact on the FPS results and thus make video hardware hard to compare?

Hey @foob,

It is a very good question and the answer is YES & NO.

Most computer monitors and laptops screens today comes with a really good resolution and refresh rate. But the biggest challenge is the Graphics card that responsible to deliver the image to the monitor. 

There are a number of other factors that contribute to the frame rate performance. Such as the graphics card, motherboard, CPU, and memory. Which is why it is recommended to disable unnecessary visual effects in Fusion, such as shadows.

Are you looking to buy a new computer? Or do you have some FPS problems with your current computer?

Hey @foob,

Are you looking to buy a new computer? Or do you have some FPS problems with your current computer?

I've got a laptop which only has an Intel i7-7600U (15W 2 cores + 2 threads) with  integrated graphics and is pretty slow for Fusion 360.

I'm in the process of evaluating whether disabling the built-in screen, disabling effects, and down-scaling my external 4K monitor resolution down to Full HD will make the performance sufficient for my casual hobbyist Fusion 360 use.

Or whether to indulge in a new Ryzen workstation...

Well, you need to consider two things:

  1. The number of components and bodies/geometry complexity.
  2. The minimum performance expectation.

In some situations, your current hardware aspects would be enough, but I can say anything about that since I don't know anything about your models.

With that said, I think you should start by disabling some of the effects and see if it helps.

PS.

Errors/Warning in the timeline and the use of the Pattern feature not correctly can also affect the performance in general.

Some data on resolution vs FPS using the Engine file from my laptop (X1 Carbon 5th Gen) with 2560 x 1440 built-in monitor + 4K (3840 x 2160) connected via Thunderbolt 3 (monitor has it).

 

1. Only laptop screen on: 41 FPS

2. Fusion on 4K screen, laptop screen switched on: 24 FPS

3. Only 4K screen on: 27 FPS

4. Only 4K screen run @ Full HD: 37 FPS

5. Fusion on 4K screen @ Full HD, laptop screen switch on: 36 FPS

 

So it seem useful to reduce external screen resolution down when running on an old laptop with integrated graphics.

@foob,

Those tests are very interesting and the results are making a lot of sense as well.

You have to be careful not to set your graphics card on too high resolution because the higher the resolution the more energy it requires and that will affect the FPS.

It's like if you build your own computer, you must pay attention before buying the power supply unit (or PSU). If the total component needs 500W and your PSU is only 450W then you are in a big problem.

The same goes for GPUs and monitors. You need to make sure they are compatible with each other! Thus, if your laptop had enough power, then your nr. 5 test result would have been like nr.4. Which is why you needed to reduce the resolution on your monitor.

Thanks for the info. This is something that everyone should be aware of.

Yep. Ideally, the parts should be matched, but things end up being purchased at different times and machine usage changes.

No way that I would buy a 32" 1080P monitor for my general desktop work! Oh well, either have to put up with it or consider upgrades...hrmm.

@foob,

You are 100% right!?
This is why I decided to build this table with the hope that it will help people to make the right decision when they are investing in new hardware.

When you are buying a new computer for your 3D software, you need to think a few years ahead and make sure you are choosing the right hardware based on actual test results and not based on public perception or on what it says on paper!

I hope the table will help you the same way as it helped me and others. If you have any idea/s on how to make it even better, then please let me know. I welcome everyone's ideas and thoughts ?
