Hi everyone,

I am planning to upgrade my 1080TI GPU. The 1080TI does a good job, as long as I keep settings on a moderate level and avoid landing at complex airports at night or with bad weather. My goal is to be able to fly every airport in any weather condition at stable 30 FPS minimum.

But even after intensive research I am still unclear what the best option is for my situation, which is:

- Prepar 3d v5 (so no DSS, Framegeneration, etc  support needed)

-3 projectors at 1080p for my home cockpit (no 4k resolution planned in the future)

- CPU: i9-13900k

- budget: 1000-1500 EUR

 

I first tried the RTX 4070, but that card didn't give me any performance increase at all. Maybe the light effects improved, but no FPS increase.

A friend of mine, who also has a home cockpit with 3 projectors at full HD resolution, got the 3090 and he reports absolutely stable performance. But I was wondering, if I really need to invest into the 24GB RAM, or if the 3080TI with 12 GB would also do the job. Sure, the extra RAM would give me some buffer.

Finally I was stumbling about the 4080. At the moment this is my favourite, I must say, as it would give me a bit more RAM (16GB) and also a modern architecture in case, P3D would support DSS or Frame Generation one day. According to online tests, the 4080 should outperform the 3090, but I wonder, why the 390 is still more expensive. Is this only due to the extra RAM? Shouldn't the 16GB on the 4080 be enough RAM for P3D?

Any advise would be appreciated!

Thanks,

Michael

If you're certain that you will stick to 3 x 1920 x 1080 resolution, then I'd consider 16 GB of VRAM the sweet spot, with DX12 and 75% of the pixel bandwidth of a 4K display.

Personally, VRAM considerations aside, I'd go with the 4080 just for its sheer processing power.  That should give you a lot of increased flexibility handling performance challenges like 4+ cloud layers, night + dynamic lighting, etc.

I'd agree the 4080 is the way to go.  more efficient with power than the 3090 plus the new features it should pair well with your 13900k.  For reference for you, I'm using the 4090 with a 14900k and I'm running 3 x 4k projectors for my setup.  I do have my FPS locked at 30, but I did try it unlocked and was getting just under 60 consistently with many settings maxed out.  It takes some tinkering anytime you do multiple displays but the 4080 will do you well.

I got an RTX4080 now, but still FPS are only slightly better compared to the GTX1080TI or the RTX 4070.

Sitting at EDDF / Aerosoft Professional with ~ 50 FPS with moderate settings and w/o weather or traffic...

I have the feeling, that I am not fully leveraging my hardware. CPU is a i9-13900k. What else would I have to do - or how much money to spend - to get stable frames on P3Dv5 with moderate settings? Maybe I should restart with a clean p3d.cfg again.....

Yes restart with new .cfg
