I'dunno man.... I'dunno... setting it to "Application Controlled" left it pretty bad and tear-y. I tried all the other available settings for good measure; off, on, adaptive, and adaptive half refresh rate. Now maybe I'm too sleep deprived and seeing shit, but I feel like that last option made a bit of difference and makes for less tearing, so that's what I've kept it on for now. Of course while leaving the config.ini option to true. I'd also tried all these settings before learning of .ini, so both variations have been exhausted.
Anyway, thanks for all the help. Hopefully there'll be some answers at some point, either a bug that can be fixed or figuring out what I'm doing wrong. But the key lies in the discrepancy between full screen and window mode, you can trust me, I'm not an expert. Or even a layman. Just common rabble. kthxgnite

I just had a brainfart and it told me to set the in game fps limiter to 1 below where I currently had it, 60, which is also my desktop refresh rate. So I set it to 59 and with the adaptive half refresh rate still in tact, I think it got rid of the tearing. But I'm not sure. I don't know what's real anymore. Too. Tired. Will experiment more tomorrow, with my sexuality. Then, if there's time, I'll fuck around a bit more with this stuff and see what happens. Please someone steal my computer and amenities in the meantime.
