What resolution are you running, which planes do you fly, and what's the highest VRAM usage you've seen?

2560 x 1440 PMDG 737/7/8 777/F/300ER Fenix A319/320/321, iFly 737 Max JF BAE 146 RJ100, FBW A32NX/A380, Flysimware C414, SWS PC12, FlighFX Citation X. VRAM never goes above 8gb. I have 64g system RAM.

I pulled the 3070 out and plugged the 3090 in and literally had 15 mins to test things out before needing to go out. I loaded the 2024 version of the iniBuilds A300 Premium at gate A20 at EDDF and with DLSS Performance and low texture resolution, I was at 8.7 GB VRAM usage. When I switched to DLSS Balanced and medium texture resolution, it went up to 9.8 and I think I saw 10.1 briefly.

As I'll have way more time tomorrow, I'll test with TAA and texture resolution and high and tweak the rest of the settings and see how it goes.

I must admit it's funny how the 3090's usage does not exceed 50% at 1080p 😁. It's the most overkill ever if it weren't for the much-needed VRAM.

I'll keep you all posted.

That's nice to hear- I've found good buyers for my old GPUs

I think you'll be able to focus on things other than OOM now. 

 

I have flown a couple of flights so far with the 3090 and here are my findings.

After swapping the 3070 with the 3090, I switched from DLSS Performance and Secondary Scaling = 2.0 to TAA and Secondary Scaling = 1.0. I also increased texture resolution from Low to High and most settings are now at High or Medium. I am still optimizing with these as we speak to ensure I can benefit from the highest settings possible.

Frame rates remain locked at 30 FPS using the sim's frame limiter, dynamic settings, and AutoFPS while lossless scaling enhances it and locks it at 60 FPS. Smooth sailing so far. In Aerosoft Frankfurt EDDF while on VATSIM with a ton of traffic, the FPS would drop below 30 in MSFS2020. Now in MSFS2024, that is never the case as the FPS remain locked and stable at 30 which is a testament to the optimizations of MSFS2024.

Regarding VRAM usage, with Aerosoft EDDF while on VATSIM with a ton of traffic, the highest VRAM usage I saw with the iniBuilds A300 was 10.1-11 GB. During cruise, it's between 8 and 9 GB. In TaiModels Cairo HECA, VRAM usage at the gate is 8.5-8.8 GB.

From these datapoints so far, 12 GB will definitely not cut it with these settings because the sim only sees 10.5 out of 12 GB. I still need to test with the iniBuilds A350 to see if it will encroach on 16 GB or not but so far, I am happy with the 3090 for $480 rather than paying $50 more to get the 5060 Ti which is weaker but newer.

Regarding GPU usage at 1080p, the highest I've seen the 3090 is at 60% on the ground and it averages 40-50% in cruise.

I hope these datapoints help inform others in their decision to upgrade their GPUs.
