lots of lag whenever I loot(PC). IT is read/writing to disk every time? Can I...

The loading never used to be an issue but the deeper I get, the more the I lag. I’m assuming it must be hard drive lag since this is otherwise a nice PC. Can I run this game in a ramdisk? I’ve done it with other games before and have plenty or ram to go around but steam seems to make it complicated, and I’m not sure how to launch it without steam (or if there is more to the game besides the exe and save data). Is it just loading and saving to the save folder every time? Can I trick it to saving to a ramdisk instead of c:, or just be able to run the entire game on a different drive?
