Just posting a me to. Got a brand new Surface Pro 3 (not a gaming beast I know but needed something small to travel)
Game ran at full res at about 30fps on low settings Prepatch with a brand new install.
Patch happens, drops to 20ish fps, second patch 12fps. Disable UI back up to 28fps. Been tweaking resolutions, etc can’t get it to do anything reasonable after these patches but everything was fine Pre-patch on a fresh install. Not sure why I’d need to install a copy of the game again within 2 days.
Surface Pro 3 Core i5 4300U, Intel HD 4400 graphics.
I’ve been traveling so I haven’t checked my other two systems for this yet. One is AMD one is NVIDIA.
