Have you ever wondered why Far Cry 3 stutters but Blood Dragon doesn't?

Not sure about Far Cry 4 as I haven't played it yet but we all know the case with Far Cry 3 - look at the ground while you run around the island and you will see the massive weird judder/stutter effect from what seems to be jacked up frame latency.

But when you play Blood Dragon it runs smooth at any framerate, the judder simply isn't there - why is that? Same engine, nearly identical assets just colored differently in Blood Dragon?

The only thing different is Blood Dragon isn't using Ubisoft's global illumination implementation. They didn't need it because the time of day never changes in Blood Dragon it's always night. And while the overall framerate isn't affected that much there is a massive difference in frame latency as Blood Dragon just runs run smoother because the buggy global illumination isn't used.

Far Cry 4 definitely does it. It's related to loading textures im pretty sure since it goes away if you turn the texture resolution down to like medium. With the latest patch and the latest Nvidia drivers though, it's mostly gone now.

Did you ever play Blood Dragon? It never stutters even with cranked textures. I really think it's UBisoft's global illumination algorithm(s) that are the problem with their stuttering.

Interesting theory, any way to test the hypothesis?

ubisoft games, you need a ssd to get rid of the stutter, not joking.

Blood dragon wasn't nearly as demanding as FC3, everything ran at 60fps with a lot less power draw on my machine.

Funnily enough I played a little FC4 on a Athlon II X4 620 @ 3.6GHz, 8GB 1600MHz, 7870 2GB @ 1200/1400MHz, 240GB SSD and it stuttered like crazy after 20 minutes. It doesn't stutter at all on a 4770K @ 4.8GHz, 16GB 2400Mhz, R9 290 @ 1040/1350 (PCS+) and a 7,200 RPM HDD even with everything turned up (except AA).

Blood Dragon is smooth on both machines & FC3 is smooth on the 7870 but shimmering textures on the 290. With Blood Dragon Ubisoft got it right, a fun game that runs well & looks just like it's supposed to. It could well be global illumination or just a game they put some effort into.

Trust me even that doesn't work.

Because Ubisoft games are unoptimized jokes compared to Eidos' games? Even Totalbiscuit said he has substantial FPS hitching in FC4 with a monstrous rig.

Not even my 850 pro can get rid of the stuttering.

Has anyone tried running one of these Ubisoft on a Ramdisk to see if that fixes it? I sort of remember reading that someone tried that.

Edit: Apparently it sort of works: http://steamcommunity.com/app/243470/discussions/0/540743757420727380/?l=japanese
