November 27, 201312 yr Commercial Member As you read this, I am aware that SLI is not working yet in P3Dv2... As I ponder what GPU I should get let me ask, what advantage would there be purchasing two video cards, say with 3GB VRAM, over a single card with say 4GB RAM? If I read correctly, two cards do not combine the ram for a total of 6GB. You are still only using 3GB (per my example). So why not get a single card with more VRAM? It sure sounds like that would be the way to go even after SLI is introduced in a future P3D version. For now I am seeing quite respectable output with my GTX670 2GB (just blurries I need to fiqure out), but thinking getting a 3GB 780 or something for now, then a 2nd when SLI is active OR just get a single 6GB card like the Titan. Thoughts?

Windows 10, (hold off for now on Win11), EVGA 1300W PSUNetgear 1Gbps modem & router, (3) 27" 1440 wrap-around displaysFull array of Bravo, Saitek and GoFlight hardware for the cockpit. Varjo and HP VR headsets for mixed reality.
November 27, 201312 yr I have the same question as probably do many. But answering what performance benefits P3D will have with SLI, would require a crystal ball and/or psychic abilities. SLI compatability and benefits is unknown and do not let anyone tell you otherwise.

November 27, 201312 yr Author Commercial Member I guess I am relating to current games that use SLI. Your're not gaining VRAM so..... you gain GPU performance with two cards?

November 27, 201312 yr I'm no specialist but if P3D uses today 99% of a 780Ti GPU as stated by some of our fellow simmers, adding more processing power (a 2nd card) would, I guess, help to compute more of the goodies : shadows, reflections etc..Not textures loading but geometry.

November 27, 201312 yr Well I do plan on purchasing a 2nd GTX680 and P3D. If we don't get any results before then, I will post back.

November 27, 201312 yr Find out whatever effects are GPU based and expect to be able to crank those up without sacrificing FPS. So I would guess increased resolution, AA and shadows at least.
