Slightly off topic, but related...

Is there a way that you could use an eGPU to share a video card between two computers without having to physically swap a cable connection?

Nope you'll need to plug them into one machine only. This isn't something you can share between machines.

Thanks - I might try moving the install to my SSD for F1 2017 as I expect to put plenty of hours in. From what I remember in the past I was disappointed how little difference it made (Borderlands 2 and F1 2012 if I recall).

SSD's can help with loading assets off the HDD however it won't help for CPU/GPU specific things like shader warming/loading. That why depending on the game an SSD will make a bigger or smaller impact on the load times. SSD's will always be better but they are not a magic bullet.

Edwin - good to know it is normal.

Seems a strange decision by the developer to have as complex a screen if it then makes loading the game slow. One thing that put me off a console to date was talk of load times in minutes.

That's why loading screens aren't complex :) They usually have a small loading animation but even that can stutter so usually dots or something simpler like rotating images are used. In some cases locked/slow opening double doors with a small corridor in-between are used to hide the fact you're loading in new assets/areas. A small corridor with a few twists and turns is another trick that's used.

This clever designs lowers the load on the game allowing it to load in the rest of the new area assets while you travel though this simple looking area. If you look out for them in games you'll start to notice them a little more :) You might in some cases get a small stutter as a door opens or you pass around a corner. The area looks simple so you'd not expect a stutter but if these happen just before a new large area you'll now know why! :)

The hint is in the name :)

A loading screen is something displayed while a game is loading assets ready to start playing. At this point there is a lot of load on the computer from CPU to GPU along with usually some file access. This has nothing to do with how MacOS deals with file IO and is more down to what a loading screen is designed to hide and that is the loading in of assets before you start that area of the game. The stutter could be reduced in some cases but that would mean less resources available for the actual loading process (as you need to dedicate resources to making sure the animations run without frame rate loss) ending with longer load times!

This is why many loading screens on complex games are hidden behind loading screens with very little animation or are hidden behind un-skippable video introductions to hide this process from the user. A faster HDD can help with some stutters as that can help with file IO however the overall reasons behind the loading screens are usually much more complex.

In Topic: Feral's upcoming project?

Great to hear EllieFeral.

A bit of feedback for what it's worth, after taking the risk and finding I could not run F1 2016 I ended up getting a PC 4GB version of the GTX680 flashed with a Mac ROM to replace my Radeon 7950.

It had to be one of these for now (rather than a newer card) because this is my only Mac and I needed a boot screen in case of any troubleshooting.

This card and Mac now runs F1 2016 just fine (I've already done a full 100% race weekend). In Metal benchmarks however it is no faster than the 7950 it replaced and the fan noise under load seems slightly more annoying.

The only reasons I went for the Mac 7950 over the Mac GTX680 back when they first came out was price (the GTX680 was significantly more at the time) and the extra GB of VRAM.

I'll now sell the 7950 Mac Edition and hopefully not be much out of pocket.

The frustrating thing though is that I've found that both users with flashed desktop R9 280X (a rebranded Radeon 7970) and D700's in the 2013 Mac Pro can run the game. Alll those cards are based on the exact same architecture and driver i.e they are all effectively 7970's by device ID and the 7950 is just a cut down version of that card.

The only reason it seems I couldn't run the game before was the one character in the device ID that separates these 7950/7970 GPUs and therefore prevents launch.

I do understand with your workload and resources you are never going to be able to officially support and test all the possible configurations out there but it does seem harsh blocking hardware that clearly would have been capable of running it.

Hi Matt,

The 7950 card is a bit of a limbo card where it both has Metal support in the drivers yet isn't on official supported lists as it was a third party card not released by Apple. email support and mention this thread and we can see if we can help you out.
