Hello there. Here are two things you might want to look for : 1) GPU overload. With both skyTEST (which add new variants of animals by himself and increae their numbers) and AV (which add a lot of them dynamically via skyproc), plus ETaC, I wouldn't be surprised if you bloated you VRAM, especially if you play with high uGrisToLoad (I believe that at 7, Riverwood should start rendering when youre around embershard mine... considering the weight of ETaC on performances... I think you get the point). Considering your specs, you should however to get arround with that if you carefully tweak ini settings for both skyrimprefs and enblocal. Trying to disable AV or reducing uGridToLoad if you have them higher than 5 should help you troobleshoot this. (Just remember that when it comes to memory overload, a "one time passed test" don't mean much...) 2) Try disabling SkyTEST. I don't have any technical explaination to backup what I'm about to say, so I won't extends much. SkyTEST is modifying some "movement type" records so some animals walks/run/swim faster or slower. This kind of modification is currently undocumented afaik. Considering the mess with everything related to animations in Skyrim, I wouldn't be surprised if it generated some issues for the game engine when the speed of the animation files isn't designed for what's mentionned in the plugins. But as I said first, it's just a guess, or rather an intuition. I'm pretty sure I also had some issue at the time I was trying mod such as those modifying the walking speed. But I just really cannot confirm that this is a fact and not an impression. Your problem might aswell lie elsewhere. As for your crashes when defeated, make sure you updated to the last version of NiOverride (included in RaceMenu 3.2.2), there was a lot of issue when the people went into the "dying" state, especially with XPMSE. It now seems completely fixed.
