Well, well. Dishonored 2 looks like it'll be a steaming pile of crap on the PC - at least until it's been updated 50 times post-launch, with early reports from NeoGAF user "Dmax3901' who has a review copy of Dishonored 2 for the PC.
Equipped with an AMD Radeon R9 290, an Intel Core i5-4690K, 16GB of RAM and running at 1080p with "mostly High settings and some of the more demanding on/off settings switched to Off (volumetric lighting, depth of field). This allowed me to maintain 60fps with dips down into the high 40s". Not that great considering Dmax3901's specs are pretty good.
He continued: "After that is where things started going really pear-shaped. I was playing with my compromised settings, putting up with the occasional frame rate dip, when I leaned around a corner and saw the FPS counter drop to 18. I turned down all the settings to Very Low and all the on/off settings to off and the frame rate didn't change. To be fair this particular room, the throne room right at the start of the game, is quite detailed with lots of flowers adorning the columns and there's several dead bodies littering the floor. But I'm afraid something weird is happening here, check out the following shots, taking note of the FPS counter in the top left".
The honesty about Dishonored 2 is refreshing, yet another game that hasn't been optimized for the PC. We've done testing that shows that Battlefield 1 can hit 60FPS on graphics cards like the GeForce GTX 1050 Ti and Radeon RX 470... and now we're here. It gets worse, with Dmax3901 writing: "Facing towards the back of the throne room I get a solid 60fps, but after turning 180 degrees it drops to 32. Going back to the door through which I first entered the room it drops even further to 18 fps".
He continued: "Keep in mind this is all on the lowest possible settings at 1080p. I figured it was perhaps a driver issue. So I did a clean uninstall and then installed the drivers Bethesda specifically recommend for AMD cards. Frame rates were exactly the same in those particular areas of the throne room. I then considered that perhaps this was an isolated incident, it was early on in the game after all, perhaps it'll even out from here on. Unfortunately this is not the case. Any time I faced a particular open area, as you can see from the following screens, the frame rate tanked. Now bear in mind not all of the below shots are on the lowest of low settings (I turned some of them back up after testing the throne room) but to be honest with such weirdly specific and enormous dips, I don't think it's got much to do with settings".
