We know what the main performance problem is, actually; it's the time spent processing draw calls. If you launch Process Hacker and point it to Fallout4.exe, it's the driver thread that eats up CPU time when in draw call intensive scenarios (i.e, Corvega, Diamond City).
Still waiting for someone with Ryzen to give it a run on one CCX, so we can see the real-world performance hit by CCX intercommunication. Would be interesting if we see the Corvega results reach 60fps.
We also need results from users with Intel CPUs, to get a clear picture of where it stands. According to that draw call benchmark thread, Ryzen is better than Core 2 Duo, but worse than Sandybridge at draw calls. Intel's later architectures only get better with them, too.
But what memory did they use ?? 3466 CL14 might make a huge difference. I was going to try this when my motherboard cam in, but I don't have this game.
But I DO have 3600 CL15, that I am sure will run 3466 CL14 on my 2700x@4.(something) ghz
OS: Windows 10 Pro 1803 (17134.1) x64
CPU: Ryzen 7 1700, relaxed EDC on, performance bias on (CB15), Ryzen Balanced power profile
RAM: 2x8GB DDR4-3466 + Stilt's 15-15-15-35 1T profile with proper subtimings
GPU: R9 290 @ 1100/1375 + Stilt's MLU BIOS
GPU Driver: 18.3.4
Motherboard: ASUS C6H + BIOS 6101 (Pinnacle-PI 1.0.0.2)
3800MHz
First Save (Corvega)
Draw Calls: ~11693
FPS: ~44.6
Second Save (Diamond City)
Draw Calls: ~7995
FPS: ~57.5
3950MHz
First Save (Corvega)
Draw Calls: ~11680
FPS: ~46.8
Second Save (Diamond City)
Draw Calls: ~7990
FPS: ~59.9
GPU clock speed would stay at ~900MHz in Corvega and ~950MHz in DC, not 1100MHz, so these tests are CPU limited. 4% clock speed increase, 4-5% FPS increase as expected from a CPU limited test.
Limiting fallout4.exe to CCX0 or CCX1 (affinity set to CPU 0-7 and 8-15 in task manager) didn't change anything. No changes in FPS value in both cases.
Looking away to the ground/sky shot FPS up to 200-250 FPS.
Let's see how it performs in a 4+0 configuration, completely disabling CCX1 and 8MB of L3 in the BIOS:
3800MHz
First Save (Corvega)
Draw Calls: ~11696
FPS: ~47.1
Second Save (Diamond City)
Draw Calls: ~7990
FPS: ~58.7
3950MHz
First Save (Corvega)
Draw Calls: ~11688
FPS: ~48.4
Second Save (Diamond City)
Draw Calls: ~8005
FPS: ~59.7
Hard limiting everything to one CCX, at 3800MHz nets me that 150MHz increase, and at 3950MHz there's an expected performance bump. Interesting, at >3200MHz and especially 3466MHz memclk, latency between CCXes is brought down to non issue levels, but still.
It would be nice if someone with a 2700x could chime in and test. That juicy 4.35GHz single threaded turbo and all the latency improvements should make a noticeable difference here.
Second Save (Diamond City)
Draw Calls: 8012
FPS: 73.4
To be honest, I don't think that anything can help Ryzen in this situation. Also, I doubt that the graphics card plays any role here.
So according to my post , Ryzen 1600x gets 47 , 55 ==> 62.5/47 = 32.9% , 73.4/55 = 33.4% , this huge different can not come from memory latency.something deeper than those
Damn, Vega doesn't have a good showing there. I wonder if the driver performs differently on Vega than it does on Polaris, and the older 300 series. Earlier results showed that AMD was pretty close to NVidia for draw calls, but your result shows differently.

[Other data]
A:My Settlement (WQHD+ MajinCry's ENB Presets+bunch of mods including SIM Settlements)
Draw Calls: 19198
FPS: 53.7(push @ and move cursor to outside of window and press Print Screen.)
FPS: 56.3(with my phone cam.Actual IN GAME FPS)
B:My Settlement (WQHD+My Reshade Presets+bunch of mods including SIM Settlements)
Draw Calls: Unknown(same save data&location as A:My Settlement. So arround 18500-19500 I guess)
FPS: 59(push @ and move cursor to outside of window and press Print Screen.)
FPS: 60(with my phone cam.Actual IN GAME FPS.)
Exchange ENB to Reshade=better FPS
Use @ and Print Screen = lower FPS
(I don't know why)
[Other data] was VSYNC ON setting. I forgot to turn off.
I'd say we have enough results now. Updated the OP with everybody's results, and will make a new thread featuring graphs over the next day or two. If anybody else wants to contribute, now's the time.
