Joker's testing at 1440p on a GTX1080 reveals that turning just 2 settings -- (1) Volumetric Lighting from 
Ultra to Medium and (2) Screen Space Reflections to 
Off -- boosted performance from 
34 fps to 58 fps (+71%).

Remember how you stated during GTX680 era that this GPU will last throughout the entire PS4/XB1 generation? Then when the OG Titan came out, I believe you said that the $1,000 OG Titan would easily last throughout this entire generation. I completely disagreed with both of those assertions. When testing Forza Horizon 3, Digital Foundry found that on an i7 5820K system ($390 CPU) and a GTX970 ($330 GPU), they had to lower certain IQ below Xbox One S's settings and 
get rid of 4xMSAA entirely just to hit 60 fps at 1080p. Conversely, in that title, the Jaguar + HD7790 Jaguar-powered 
$200 Xbox One ran Forza Horizon 3 runs at roughly 
High quality PC settings with 4xMSAA, albeit at 30 fps.
MS just announced that Gears of War 4 will have an 
11GB (!) day 1 patch for physical disc owners.
The reason I am bringing this up is that just like last generation of consoles and the generation before, this generation of consoles will continue to have horribly optimized console-to-PC ports.
BTW, Quantum Broken looks like washed out soapy garbage with Scaling ON. When running the game at proper PC resolution with Scaling OFF, the game looks miles better.

Now that we have established the comparing performance of this game with Scaling Off is a complete waste of time since it wiped the floor with IQ, what do we get?
1080p:
We get a game that 
cannot even maintain 30 fps locked on a not even a 3-year-old $700 780Ti, a $550 R9 290X and hugely popular $330 GTX970.
We get also get a game that cannot maintain 60 fps locked on a 2016 $700 GTX1080. Pffff! A joke.
Naturally, when running the game at native resolution with scaling off at 1440p, the performance is horrendous. This is worse than Batman AK.
This game is the very definition of an optimized pile of ****, regardless whether it's run under DX11 or DX12. The DX11 vs. DX12 argument is irrelevant in this case entirely because the developer has no porting skills whatsoever to begin with. If a developer has no track record of well optimized PC games (DICE) and no track record of great console-to-PC ports, then how can we objectively even make a judgement about DX11 vs. DX12 in this title? Frankly, the entire title is broken.
I refuse to pay even $5 for a 2016 PC game that requires very high-end PC hardware, the likes of 6700K/6800K OC and GTX1080 and still struggles to hit 60 fps at 1080p at all times, unless it looks like the best game in its genre, if not in all of 2016.
It's shocking just how optimized DICE games are compared to the vast majority of AAA garbage that gets released. I guess these developers think that 30 fps locked is a satisfying cinematic experience, so what's the big deal, right? /s
The fact that Remedy first released the title as a DX12 game under Windows 10 store, but then reversed their stance and released it as a primarily DX11 title under Steam only goes to show they themselves either don't believe in their own DX12 optimizations, simply lack the resources to do it properly, or most likely never made the title with the intention of porting it to the PC and when MS told them it's going to the Windows 10 store, they were extremely time constrained and released a turd. Knowing that, what were the chances that a short period of time after that they would dramatically improve the performance for Steam? DICE proves that you need a lot of alpha and beta testing and many, many months of optimization to arrive at a well-optimized PC game. So many of these new AAA games are now released as betas, we are asked to pay $50-60 USD + $30 DLC and then it takes 6-12 months to patch the **** out of these games to get them to run better (which isn't always the case either). No wonder so many PC gamers flat out stopped buying $60 USD AAA titles at release...it's like we are paying them to be their beta testers.
