This thread is dedicated to sharing the performance we're getting from the game and collecting some data in order to better understand why the infamous stuttering problem that some people're having is caused. I'll start with my values. My specs: i7 4790, Sapphire Radeon R9 290 Trix O/C 4 GB VRAM, 12 GB DDR3 RAM. Here's a video of the performance in one of the most stutter causing parts of the map: http://goo.gl/R7nH0Y In this video, the game runs maxed out at 1080p, anti-aliasing set to Temporal SMAA, using ultra textures thanks to Maldo's Texture Hack v3. It's capped at 30 frames per second in order not to have occasional stuttering caused by fps drops, as the game's frame rate is extremely jumpy and it goes unstable especially while you drive around the city. Here are some of the values I've monitored while playing the game: 1080p/TSMAA/Ultra Settings/Textures on High Maximum VRAM Usage: 2.6 GB Maximum RAM Usage: 3.7 GB * * * * 1080p/TSMAA/Ultra Settings/Textures on Ultra Maximum VRAM Usage: 3.3 GB Maximum RAM Usage: 4 GB I'm using AMD's 14.6 RC2 drivers, and Ubisoft's 1.3 patch. Some users reported that 1.3 patch caused more stuttering for them, in my experience it seems like did not affect the performance at all. --------------------- Let's get back to the most important question: how did I get rid of the stuttering? Mods can't do much about the performance as I believe the game should be further optimized by Ubisoft themselves. If anything, the engine tweaks that came with the mods made my performance even poorer so I don't use them. The problem solver for me was upgrading my old CPU (i5 2500) to i7 4790. Right after the upgrade, without tweaking anything, the stuttering issue was gone for me. But the strange part is that some people with similar configs report that they cannot get rid of the stuttering whatever they do. It makes me conclude that the game acts differently on every config for some weird reason. I have a friend working at a very high profile gaming company, and he said that when they tried the game at their office, it worked differently on every config with similar specs. He says the game runs fine on his own computer at home, but not at work with similar configurations. So what's the issue with the game's poor performance on PC? I believe the issue might be VRAM here. As noted by the values I've provided above, the game actually uses more than 3 gigs of VRAM when it's set to ultra, even though it's stated in the in-game graphics menu that you're required to have 3 GB VRAM in order to get the game running maxed out. That might be a bit far from truth, and the cause of the stuttering might be the shortage of VRAM as I believe the game is designed to benefit from the unified memory of next-gen consoles (PS4 having 8 gigs of VRAM). I believe that's the point where people who spend their money on graphics cards with 4 gigs of VRAM get their money's worth. Keep in mind that the game is highly CPU dependent as well. Jonathan Morin, the creative director of the game states that you have to have a CPU with a passmark score of 9.000-10.000 in order not to have a CPU bottleneck when you have a high-end GPU. The source of that statement can be found in the following link: http://goo.gl/0WPwTL VRAM issue is further evidenced by the following video: http://goo.gl/cFPeM3 So that's it, guys. Let's share performance so that we might be able to help people. How is the game running on your rig, what did you do to get rid of the stuttering, or is it still plaguing your game? What might be the possible cause, and what would you suggest in order to get it to work better? Cheers.
