Hi!, sorry for the huge delay on this response.
If you send me an email to my name here at gmail.com I can get you in the discord and help sort some of these out.
Ill take a short shot at some of it here.
1. Need to let my programmer know this. Weve had nothing but problems with recentering on steam
2. First Ive heard of this. Can you adjust your IPD manually?
3. You dont have to reload the gun. Just buy or find some more ammo. It holds 99 shots.
4. For sure. Still a lot of work to be done on that area. You'll be able to completely customize it eventually.
5. For some reason steam defaults to 110+ super sampling. Lower it to 100% and you should be fine. Steam overlay does indeed cause issues.
Again, sorry for the delay. Please do join us in discord if you can.
