Yep, that's a true point you got there. So, disabling PRP-SS2 would be the wise thing to do? Surely, PRP-main is a must-have mod, or is that a tricky one too? It's not mentioned in the Mod Conflict list.
I don't use PRP because from what I can tell, it needs a lot of compatibility patches for various mods. And since a lot of those patches are outdated, in my opinion you're likely to see CTD due to that. In other words, CTD with it installed or uninstalled. I haven't tried it, so I can't say which would give fewer CTD. But I don't want to go through the whole complicated install/config process with that mod unless I'm sure it's going to be compatible. That's the problem when using mods that need compatibility patches, and the base mod is still being updated often. By the time a patch comes out for one version, the base mod has been updated again.
I do use the "Colter fix", works great. But I'm not seeing any problems that PRP is likely to fix. Any CTD that I'm getting are from something else, outside of what PRP addresses.
I definitely get more CTDs the longer I play.
I completely understand the solid advice from Spacefiddle, but am shockingly lazy, and just reading the installation instructions for Buffout gives me cramps. One of these days I'll make the effort. My (for lack of a better word) unwillingness to install Buffout is what has stopped me from posting a lot (and I mean a lot) of questions on here. I expect that with some patience, I could figure it out.
I love how this community helps each other out like this, sharing knowledge and tips. So awesome. I have also recently installed PRP, and understand how difficult it might be for the developer to keep up with the patch cycle of SS2.
Edit: Oh! One question... I have an aging GPU. I've read on here that scripting is tied to frame-rate. If I can upgrade my GPU, would this help with script lag?
Buffout 4 was actually very simple and fast to install if using the instructions. Took me a few minutes to figure out how to use the crashlog tool, but once I messed with it for a couple minutes it's easy. My problem comes from crash logs that shouldn't be happening, and so far nobody has really offered to help find the problem. But if you're getting CTD for something more common, it's easy (or at least easier) to look up a solution to fix it.
For improved frame rates, GPU alone isn't the concern. CPU, RAM, GPU, HDD vs SSD vs NVME (m.2), even your monitor can make a difference. I recently built a new PC (end of Apr 2021) and it's running everything very well under Ultra settings. But I also use the
High FPS Physics Fix mod to make sure my game doesn't go nuts when my FPS is generally above 80-100 even on full Ultra. Note that I'm also using a 165Hz monitor set to 144Hz for now.
SS2 wasn't released yet when I was using my last PC, so I can't use it for comparison. But for example, I run Skyrim with a ton of mods, several of them are very script-heavy (papyrus stuff). Having built this new PC with an NVME instead of my old drive, that alone has given me a huge performance increase regarding script load. I also have a newer CPU and RAM, but my RAM count is lower. My graphics are pretty close to the same as before, due to lack of availability at the time to buy a better model. So from my experience, a newer GPU can help, but I think where you'll see the biggest gains are from using NVME or at least a good SSD instead of traditional HDD, and a faster CPU/RAM clock.
