I told myself I wasn't going to buy the xpac (which it hardly is as it's basically just a paywall for extra guns, armor and the saddest amount of content a company like bungie and activision could afford) until you fixed the current issues with the game, but the way you have set your game up you can't really afford to miss game time if you're a completionist. In the beginning the game ran wonderfully at a clean 100+ fps on high. Somewhere along the lines since then you have released an update that has completely -blam!-ed the optimization on the PC port. I've tried everything on my end from deleting the CVARs file, uninstalling and reinstalling, scanning the game, changing video card settings, reverting to older drivers, and even a clean install of windows to my rig. YOU have -blam!-ed up at this point, not us. It is extremely frustrating when searching for a solution to this problem that you copy and paste an explanation of how to delete the CVARs file. I'm completely regretting buying the xpac and I wish there was a way I could refund all the money I've spent on this game. You have completely -blam!-ed up the optimization on the PC port. Please fix this, it's ridiculous.
