[2022] Things That Might Help Allieviate Frequent Crashing

I'll start at the beginning, I was born a long time ago on a farm, out in the wild... okay that might be going back too far... While using patch 1.5.0 I was getting frequent crashes sometimes every 5 to 15 minutes (some days, and then some days none) and lately I've only had one crash in probably close to 25 hours of play. Now I admit that I have also updated to 1.5.1 so that could have stopped my crashes but I started using these 'techniques' a few days before I updated to 1.5.1 (and I didn't crash then) so I'll still put this info up just in case it helps someone else. (Anything in brackets () means this is just editional info and can be skipped)

1. Don't leave the Ubisoft launcher up when you're not playing or don't plan to play for a while (if it's been open for ages a simple restarting might help too)
2. Once you get past the splash screens (where it says "press any key/press A to start") leave it for a minute before pressing the button, this is especially important if you've restarted your PC since last playing. (this is to given it time to finish loading the main 'framework' of the game. I'm not a programmer so I can't explain it well but when you restart your pc any temp files a game has in use will be cleared on a restart, (Dragon Age Inquisition is a good example of this as it takes longer to load the game after a restart) so giving it more time is basically letting the game finish doing its thing in case it needs additional time)
3. Give it 10 seconds before making a save in-game. (Skyrim taught me that games have scripts and things running in the background, (which can cause problems in your save if these aren't allowed to finish or mess up in some way) so I got into the habit of stopping my character from moving, making sure nothing is about to attack me, and then saving, again, this only takes about 5 to 10 seconds, basically you want to limit things loading in the background as much as possible).
4. Don't QuickSave Immediatley after leaving a menu (start menu, map, inventory etc) (This is because as you've probably noticed this game's ambient sounds take a couple of seconds to start after you leave a menu, and, as mentioned above I like to give a little time for things to settle before saving)
5. Try not to rely on AutoSaves (As alluded to above I don't like the idea of using saves which might have saved 'mid-script' etc. Autosaves just happen when they please so they don't follow my rules [SHAKES FIST] so I don't use them. I know this is easier said than done with the amount of times this game crashes, so I'm not saying don't ever use them, just try to make your own saves more frequently... talking of which...)
6. Make plenty of Manual Saves and Quick Saves. (YES, I'M TALKING TO YOU [POINTS]. With any open world game, like Witcher 3, Skyrim, ACV, ACO etc there's a lot more going on in the background than say, something like Doom Eternal (this isn't an insult [pushes the Doom fans back into the cupboard] so it really doesn't make sense to keep using only one save. You might mess up that save in some way and then all you have to reply on is Auto saves (and this game can sometimes Autosave 5 times in a minute and a half) so do yourself (and your sanity) a favour and make a lot of saves. As an example I'll explain my save routine... get comfy... not that comfy though, doing it like that is bad for your back) I'll normally use Manual Saves before/after important situations such as before starting a new mission, finishing a mission. I'll make a save before a quest, then during that mission I'll use QuickSaves (like, before getting to the 'action' area (fort, camp etc) then if the quest moves on to somewhere else, I'll make a QS after finishing that part and then when I get close to the next 'action' areaI'll make another. I'll do that until I finish the mission. (I'm running out of words for mission and quest, can I borrow your thesaurus) This may sound tedious to some but if the game crashes I rarely have to replay more that a few minutes of gameplay to get back to where I was (excluding River Raids and 'Red' areas). I'm not saying you have to follow this to the letter only explaining how I do it. (Also F5 on the keyboard is QuickSave so it's not too laborious, think of it as a mini workout for fingers and brain lol))
7. If you think a bug has started in your game go back to a previous save ASAP... maybe. (Some bugs can become stuck in your save file in games so if something funky happens and reloading the game doesn't fix it then it might be worth a try to go back to a point before that bug appeared, and if you followed my advice above (or you make plenty of saves anyway) then this shouldn't be a problem [POINTS AGAIN].
8. Try not to have too many unfinished quests open at once (what I mean by this is don't start an arc in england, do a quest or two and then bugger of to france to do that DLC. The only reason I brought this up is because I think I've seen it mentioned maybe 3 times that this has caused an issue for some players so it might be worth considering).

I've always done most of the above (I started using these after having some painful times on a modded Skyrim) but the ones I've added to my routine lately (because of the frequent crashing) was number 1 and 2. I'm not saying these are a magic fix-all and yeah, it simply could have been patch 1.5.1 that fixed my crashing but some people are still having the frequent crashing on 1.5.1 and mine has stopped... so maybe something else is working, either way the things noted above are good things to use in any open world game (IMO).
