Anyone else on PC getting weird framerate issues? I realize laptops aren't the best for gaming, but I don't have a real PC at the moment. This issue happens no matter what settings I run the game at, even lowest at 800x600 resolution.
The game is a rather odd duck performance-wise.
I did some rough profiling when running the game on my admittedly ancient Core 2 Duo T9550/ATI Mobility Radeon HD 4670 laptop, and it's a very, very CPU bottlenecked game. Changing the resolution down the lowest I could go (960x540) and all around minmal settings only brought it up to 43 FPS, so the sweet spot ended up being 1280x720p, High Textures, Low Shadows and minimal settings for everything else to get the standard 30-ish FPS console experience.
The first part of the game (the dream ship battle bit) chugged to the single digits at times, even with minimal settings.
I had a look at GPUz whilst running the game and GPU% usage was really low (i.e. never hitting 100% even with Vsync off), which is normally the case in games that are properly optimized no matter how I tweaked the graphics settings.
The game also only really effectively uses 1 core of your CPU; I discovered this by experimenting with the core affinities in the Task Manager (making the game only use 1 core yields little to no difference at all as compared to using both cores). Even then, single core CPU usage is decidedly low, leading me to suspect that there is something else along the chain that is problematic.
I've also got a sinking feeling the game uses the CPU to render certain graphical assets (like GTA IV did with the shadows).
The way the game tanks to extremely low framerates (13-15 FPS) in certain areas of inactivity (places you wouldn't expect it to tank) is also rather annoying and brings to mind another poorly optimized PC port which was Dark Souls. (unoptimized mutlicore CPU usage coupled with low GPU usage which leads to an overall poor framerate which is unaffected by tweaking graphical settings).
Frankly speaking, after being used to a solid 1080p30 experience with Dark Souls II's engine (Mostly High and Medium settings) on my crappy laptop, I'm rather disappointed with this game in terms of its performance.
