FPS drop every 10-15 seconds

Im not sure if these developers know how to implement a HOTFIX yet. This Flight sim seriously serioulsy needs one. The last patch completely broke the game and there is no way to fix it but to wait for a new patch. Well I have been waiting for over a month now for a fix to thos mess and the update that was supposed to arrive has been pushed back even more. I understand they want to make this patch but if this patch does not fix the low fps I will lose it. This is why updates should be rolled out in stages, so in case something like this happens, we can go back to a previous build that worked just fine. Being stuck flying at 15 fps for a month when before the update I was getting 45+ fps, this is an absolute disaster. If anything, I just wish the devs would get serious fast about implementing stable performance hotfixes. Every time I fly I get more upset because I knpow what this sim used to and SHOULD be like and waiting this long for a proper solution is plain stupid.
