Forgive me if this post is bad, I've tried to search for solutions everywhere I can think. So here goes... My system is a Ryzen 7 1700, (OC'd to 3.4ghz). 32gb DDR4 PC3200 G.Skill Trident Z RAM, (actually running at 3200) AORUS 1080ti GPU Windows 10 I've attempted multiple monitors. My gaming monitor is a GSYNC ASUS 3k, I own an ACER 4k, and a Samsung HD monitor, all with similar/perplexing results. So I'm only getting between 55-85 FPS in-game. While in orbit, the frames hit in the 260s+, but once I fly into a location, they go very low. The strangest part, it does NOT matter what my graphical settings are set to. Low vs High settings give almost the exact same FPS results. It doesn't matter what changes I've made to setting in the Geforce control Panel, I have my computer's power options set to High performance. I don't have an integrated gpu, but have set the windows graphical settings to "High Performance" there as well. Also, multiple settings changes in GeForce Control Panel see no noticeable changes. I've reinstalled D2 multiple times. I even completely wiped my HD and reinstalled D2. No change. I've tried D2 on a regular HD and on an M.2. I've checked my CPU and GPU usage while in game, my CPU is around 30-40% usage, GPU never goes above 60C. The game used to work just fine, but it was years ago. I only came back to try on PC after cross-save, and noticed the issue. Other games seem to work fine. Something else to note, the game seem to give me slightly BETTER fps on my 4k monitor... which I found odd. The game also runs around the same fps on low settings on my older gaming laptop running a 980m and an i7 mobile. Any thought or advice? I'm at my wits end here. thanks!
