The cities are actually cpu!!!

right..... then the mistery gets deeper for me. Why over cities the cpu (9700x) works like a charm, no drop, and when over the bombers it goes 90-drops till 50-up again at 80-drops at 60+-climbs at 90-stays at 90, despite the fact that I still chasing those big fat ladies ??

I have been using capframex to try to get to the bottom of it.

My guess is in flatscreen it is still very playable over cities vs vr. But it also isn't as bad as heavy ai bomber mission. My guess is that all of the ai is calculated on a single thread, or potentially in the bombers there is also all the physics of eaxh bullet... cities it probably has to do with shadow calculations for each buildings and the amount of polygons the cpu jeeds to prepare- which is a lot of work, but not tye same kinds of calculations involved in 60 plus ai planes.

I run it on a 14700, RTX 3070 8 Gig, 32 Gig RAM and the only thing I throttle back is the 4K textures.  When I run them I eventually get a VRAM warning.  But, I have the FPS set to 80 and it never goes below 80 even in crowded skies so you should be fine

Thank you JG14_Jagr. A light on the horizon 🙂

Smart, SMART, SMART ! Wow! you're smart, man ! I never thought of that.

I'm not a professional. I very well may be wrong, but from what I am seeing it is at least plausable.

What do you see in % load - RCTRL backspace in game during bombers intercept?

60-70%

I had thought/read somewhere that they were optimizing the AI for Korea to be less cpu-intensive by not modeling every crew position, etc? I also thought the AI was going to be approached differently (using simplified flight model away from player's mission) to allow for bigger formations? Seems like it still isn't well-optimized; yes it is Early Access but it seems like Cliffs of Dover again regarding performance (particularly in VR).

The B29 has a second simplifiedFM/DM, it also has a detailed FM/DM. That can allow larger formations. I don't know what's used in the black thursday mission. 

This is nothing like Cliffs of Dover.

Lol.  Clod was unplayable at release.  Completely and totally unplayable.  There are plenty of people playing this game right now.  Just stop.

[Valis]

Just got back from online and it ran perfectly - even in a flak-ridden furball it ran very smooth.

If the devs can reproduce that performance but with AI instead of humans I'll be over the moon.

Love the sound!

Your front yard looks suspiciously like a plane.

They definately did improve it! Put 60-100 ai aircraft in a mission in GB and see what happens.

Very interesting, but i don't quite understand it. Regarding the (in)famous bomber mission, all settings as previously shown:

- while capped at 90 fps i experienced drops as low as 48-50 fps, with accordingly stutter, until while i was still attacking the bombers, the FPS glued itself at 90 

- this night i capped at 60 fps: same ....everything, no FSR, the FPS never dropped a bit from 60.

Why? i don't get it. shouldn't it have also dropped to 48-50 fps as before? Any ideas why ?

The CPU prepares frames for the GPU to render. Capping the frame rate reduces the CPU workload, leaving more CPU time available. Since bomber AI is CPU-intensive, the freed-up CPU cycles can be used for AI simulation instead.

Those are pretty hardcore specs, with a machine meeting the recommended ones approaching 2000 euros.

[Megakill]

It’s a new platform that hopefully will stay “modern” for the next 10 or so years…

exceeding, and not by a small margin, at least here in the eastern Europe. for a 9700x/9070xt/32 Ram 5600mhz/good PSU, API i've paid 1800 euros, after huge research, and a better rig would have been beneficial. But i had wife limitations.

But so far, well, i have to say : it's worth it.  So far (yes, plenty of content to be done and bugs to be squashed and optimization to come, and AI to rise and, and....) the game exceeded my expectations. I was thinking a GB on steroids. It's not. It a brand new beast, but with obvious legacy.

well said! ANd a new beast with legs to travel means its really built for today and tomorrows hardware. Hopefully RAM prices will come down soon. Good CPUs at least are still reasonable price.

[FuriousMeow]

For best performance and stability everyone should also be keeping their drivers and firmware up-to-date.

I do a clean install of nvidia drivers at each release, this isn't the early 2000s anymore where a certain driver stack - or a strange amalgamation of driver version bits are needed for GPUs and some games/sims to run well. Mobos also should have their chipset drivers kept updated, and their BIOS - even though its annoying to have to set things back up again. 

Since moving back to AMD from Intel with Zen3 there's only been one bum firmware I've run into and that was likely related to the 5800x3d where the 5800x could no longer hit the boosts it could prior to the firmware that didn't support that CPU model. With Zen5 though I haven't had any issues with keeping the BIOS on the latest release.

I've been flying in IL2-GB/FC in VR quite nicely with my rig below:

INTEL Core i9 12900K 3.2 GHz, RTX 3090, 1TB NVME Gen4 SSD, 32G DDR5 RGB

However, it's been giving me some unsettling vibes and weird errors recently and I'm thinking I might have to replace it soon.  I want this to be my last upgrade/replacement for a while, and I also want to make sure there's a reasonable chance the new rig will be able to handle IL-2 Korea in VR (at least with my current G2 Reverb - not likely to be able to replace both the PC and the HMD any time soon).  So, I've been thinking about something like the following:

AMD Ryzen 7 9850X3D 4.7GHz, NVIDIA RTX 5090 32GB VRAM, X870 Board, 2TB Gen4 NVMe SSD, 64GB DDR5 RAM 6000

Just starting my research, so I'm not yet fixated on these specific specs, and I'd love to hear from any folks here running anything close to this as to how they're doing with IL-2 Korea in its current state and whether there are any specific elements/items of the new rig that would make more sense for use with IL-2 Korea.

If your only planning for Korea it never uses much more than 16 on the RAM, so you can grab one of the 32 sticks and wait for the inevitable price drop for the other.

that might be an overkill. still, from what i've seen, performance is 50% hardware and 50% optimisation. on my 9700x/9080xt/32GB 5600mhx i run forza horizon 6 with everything on ultra, ray tracing, etc capped at 180 perfect. still, in Korea before 004b capped at 90 was ok most of the time, after patch i had to capp at 60 to stay smooth. graphics not at full, 1440p

Try to ask @Panzerlang, i think he has pretty much such a rig.
