Does Prepar3D support SLI (Scalable Link Interface) for Nvidia cards

Post by Experimentalist »

Hi

Nvidia graphics cards have what is known as a Scalable Link Interface (SLI) to improve graphical performance by supporting multi-GPU technology in video games. Does Prepar3D support this configuration?

Thanks.

I believe P3D will run with SLI-connected graphics cards, but you're not likely to see much performance improvement with SLI.

The CPU and its clock rate is what matters in P3D.

SLI is dead Jim...

That said if you can afford a 4090 card you'll get fantastic performance from P3D provided you also have a suitably high powered CPU to match.

I reguarly max out my 3080Ti - if only I could afford a 4090... :-(

Also AMD GFX cards have a frame smooth motion action in their latest driver set I believe.
