Non-forum user here, since 2.9.0 OB was introduced I started getting massive freezes every 4-5 seconds which do last about 5 seconds each time. I've never had issues running dcs on medium-high settings, but after 2.9.0 it became unplayable. I found one way in particular to fix it and (besides installing Lasso as @Checkmate suggested), everytime I spawn in an aicraft I have to switch my CPU affinity (got 4 cores, i5-7500) from 4 to 1 core. Having done this, I enter the game back in and have to alt-tab again and set CPU affinity again to 4 cores and I have no issues thereafter, almost running smoother than I usually did. ED, or whoever is responsible for tweaking this kind of stuff, please fix this soon because one of my friends is facing the same issue. I also have a crash log from the last mission I did and if useful and requested, I'll drop it here. Please, someone help me with this programming hell.
