Sorry all, I didn't see any replies as I didn't check the notification box. NOOB!
Thanks for all the advice. I went ahead and bought a (relatively) inexpensive touch screen and downloaded the 4.0 beta. I had a few teething troubles, but today I managed to sort it all out. I think I went about it through a very tortuous route, though!
@jph - I'm using nvlink. By profession I am a videographer and 3d artist and with the 3d especially it helps to combine the vram.
Thanks again for your help.
Hi,
Thanks for clarifying the Bridge.
Unfortunately, there is so much MIS-information on the emptynet regarding such a new technology. (and almost any other subject!) NVLINK, as I know
you know, is not a master / slave config. it is not SLI .. yet many seem to answer queries with info grabbed from fora regarding SLI with little research. So when you, who have successfully used the technology in a real world situation ask for specifics it is 'almost' impossible to sort the chaff to get a real answer as so little use the latest tech, but many have used the completely different SLI and tend to answer based on misinformation - that also includes google searches etc - and, some of the more 'respected'
sites.....
I think your usage case is interesting. (very interesting)
Can I suggest you speak to the guys that know ?

Ask them about your specific usage scenario.
When programs don't specifically support dual gpus (99% of them unfortunately............
) then it is so difficult to find the best solution.
MSFS is, like most (all ?) sims on the market for flight - processor bound for most of the time. (and definitely not supporting dual gpus in any config that makes any difference !. Usually it makes things worse due to lack of specific coding - which is actually understandable for such a niche market .
I have both a 2070S and a 2080ti. They are both in different rigs, however, it is easy to swap out a gpu for testing. The main rig is running at 5.2 GHz (all cores) with a 9700k. All settings at max apart from level of car / vehicle detail. (I dont use aircraft on ground or reflections greater than the first setting.)
Test have shown little difference between the cards apart from when the abysmal weather system in X-Plane is used... then the thing can be brought to it's knees by AI Filtering. Also, in general use, the processor can be dragged down by the amount of vehicles in use which is not a setting that can be controlled via the interface - it needs to be set manually in the dataref tool.
Anyway, basically, with absolutely NO weather in XP, then the gpu (2070s to 2080ti) makes little difference, as the so called weather is added, then the gpu can easily become saturated and become gpu bound as opposed to processor bound.
the bottom line is - as far as x-plane (I know jack about msfs 2020 - however I 'suspect' it is similar') then adding a fourth monitor running Air Manager to a single gpu will make such a small difference as to not be noticeable - both with a single 2070s and a 2080ti,, There ARE notable difference in the performance of the sim between gpus, but with AM, you can remove that from the equation as it is so little load as to make - for all intents and purposes - no difference as it is so lightly loaded.
Definitely ask your specific questions to NV. I can offer direct 2070S and 2080ti comparisons, but, unfortunately not with msfs as it doesn't offer what I need (at the present time). With XP and ORBX UK, the graphics, I believe, are far better in the UK (not the rest of the world) than msfs - .. however, I only fly in the UK so it makes no difference to me. - the 'weather' is, I believe FAR better in msfs, as anything must be better than XP weather.
Joe.
