DCS on GTX970M

[Kirpano]

Hi all.
I was wondering if i can run maxed out DCS with laptop GPU GTX970M (3GB version, 16GB RAM, i7 6700HQ).
Is there anyone who owns this GPU and can share experience?
Thanks.

No, the only real difference in your system from mine is I have an 870M, and while I'm pretty sure the 970M is quite a bit better I have to run in low settings to maintain as close to 60 frames at all times.

You might be able to get away with mostly medium settings, but certainly not full.

Mobile GPU are poor in performance comparing to discrete GPU you find on desktop computers.
There are limitations you have to accept when running on those (if they meet minimum requirements).

Thanks you all for contribution.
My testing notebook have just arrived.
I set all on ultra/high/all slides to the right - >
results:
During free flight (aka i am almost alone on map) it kept 60FPS even near ground.
When i flew mission CAS-difficult in SU-25T it was around 40-50FPS up in the air, but dropping near ground to 18-25FPS.
I am quite impressed how well GTX970m handles DCS :-).
It is testing laptop so i did not want to activate any paid modules, but still do you think it would have had some impact on performance to use some advanced models?

Some aircraft are very demanding on the CPU so I would not recommend any laptop for serious sim-usage. Desktop will get you better performance for lower cost.

Remember that adding more different units (friendlies and enemies) will add more demand on rendering power: just testing aircraft itself is not enough.

Cities and places with more objects will also have more demand on resources than empty areas.
We don't know yet what kind of demand next terrain upgrade will have in 2.5 but ensuring easy upgrades is good idea.

I have a powerfull desktop for sim purpose. I was just wondering what the actual performance of this GPU is.

[kazereal]

For comparison, when there is only aircraft and some sky to render (FC3 level simplified systems) I can get 250 fps on Radeon 7970. When flying near ground between cities it can drop to 50 fps. It depends a lot on what kind of settings you have.

Aircraft with advanced systems will require more CPU power for simulations so that kind of framerate in the sky is not possible on my current computer in those cases.

You do need to consider whole computer when estimating the performance of DCS on a computer.
