To be safe do this:
1. the hack have 2 options for cleaning screenshots. If you not select any (if you uncheck it both), then all ss will be blocked and will send black screen. I do not recommend to block the ss. So you must select one of both cleaning ss features (autoSS or ScrollLock button) which you prefer. You can test it first to be sure all is OK: activate hack, spawn in the game, select one of both SS features (for example AutoSS), wait 30+ sec., press F5, wait 30+ sec., press F6. Go and see the the .bmp files. _spoofed.bmp _provided.bmp must be clean.
2. _spoofed.bmp _provided or _taken.bmp must be clean and must not show any hack. They are located one directory up of your game folder.
3. when you play and see some ss messages, minimize the game immediately and see bmp files. They must be clean. Keep eye on .bmp files just to be sure all is ok. It is good to take a look at bmps once in a while, if you like.
4. Which ss feature to chose, AutoSS(automatically clean screenshot) or ScrollLock screenshots? How they work read above in the dev log. If you chose AutoSS keep the ss timer as low as you can. I think less than few seconds is unnecessary. I use it on 15 sec. and no problems, I think no need to waste my CPU, but I dont want to impose my opinion, you can use 3-4 sec. or even less 1 sec if you have plenty of CPU to waste.
5. If you are still eager to use shitty FPS counters or other hacks over this hack, then test it first and look .bmp files to make sure you not glitch anything
6. use last version. Do not play with old versions
7. remap the hack main keys, at lest, END DEL and if you like F5 F6 and others buttons (just edit imgui.ini). Change it once in a while if you are too paranoiac. To create imgui.ini press F12. You will find it one directory up of your game folder. Allegedly BF1 logs your keys, so if you press special keys like END/DEL will trigger suspicion, that's why is good to remap the shortkeys if you like
8. Do not play with norecoil only. Killing without waste of bullets (accuracy goes high) is detectable, as well as others shits like bullet speed, bullets per shot and others. Use norecoil randomization on 2 or even 3. Do not make headshots, do not rage.
9. Play in bordless mode only!
10. put game to another dir, not "X:\Program Files (x86)\Origin\Battlefield 1" because settings imgui.ini and .bmp files will go in Origin folder. Put the game in another folder e.g. X:\Games\Battlefield 1 so imgui.ini and .bmp will be saved in X:\Games\
11. play on DX11, not DX12. English version of the game. For other languages I am not sure. To inject the hack I use Extreme Injector v3.6.1
