Severe FPS loss specifically when passing the Imperial slug-grinder scenery

I’ve noticed some extremely bad FPS drops when passing through the area where giant undead slugs (the ones that look like Spymaster Zerrick) are being ground up for parts.

While walking through this zone, my FPS (which I normally keep capped at 60 and never dip below that) drop to 10-20. The issue is resolved as soon as I walk far enough away from the slug-grinders that they’re no longer on screen; even within the same zone, there are no problems unless I’m actually looking at the slugs grinding machinery.

This happens every time I pass through this area. It happened in the campaign version of the zone, and still happens in the Monolith of Fate version of the same area.

Video demo (the FPS loss shown here is slightly worse than I normally experience in-game due to running the recording software at the same time, but it gives a good idea of how night-and-day the difference is in this zone):

Hey…

Thanks for including the video & your system info/files…

As you know LE is in beta so things like what you describe do happen - even on higher end systems…

A few things:

  1. Its really tricky to diagnose laptop performance issues as the manufacturers have to perform magic tricks to balance power, heat and performance… sometimes these present as odd things - especially with beta applications… It may be that this could be a side effect of the two variables. I realise that you are using a high end laptop with a 3070 but I am just pointing this out…

  2. There are various places and events in the game that do create fps spikes - lots of mobs, certain maps, lots of skills proccing, lots of minions etc… The only way to deal with these right now is to be conservative in settings to minimise the impact. Obviously when the devs deal with these things, then we can all dial up the eye candy again.

  3. What is your CPU & GPU usage & thermals doing when you walk through this area and play the game generally? Do they spike up suddenly? Are they fairly high all the time?

  4. Your in-game settings would normally be ok but the game is in beta and I would recommend that you do some logical testing with all those items that you have on High. I have a feeling that one or more of them in combination is causing this particular spike for yoyu… High end desktop users have found that sometimes dialing back to medium or less improves things for them dramatically. The easiest way to start this testing is to set everything on very low and walk through the area… for reference I get 60fps on an i5-7500/1060/16gb without any stuttering in that particular place even killing mobs - settings on 1080p, 60fps framelimit, very low or disabled settings.

  5. I see your graphics card driver is from Jan 2021… there are April releases… Please update those… and while you are doing that, please make sure that the OS is patched and things like bios updates etc are up to date…

  6. Lastly, the dxdiag shows some app errors etc… at the bottom… You may want to just check your system logs and make sure there arent any serious issues on your system that need to be checked…

Updated my graphics drivers, set graphics settings in-game to Very Low, issue persists:

I don’t typically keep close track of my thermals, but guessing based on fan speed, my temps go up when gaming in general compared to baseline, but I haven’t noticed any specific spikes during these FPS lag events associated with this scenery.

As above, now updated these. OS was already up to date.

No clue what this is. I don’t know enough about what dxdiag reports are supposed to look like to know how much of a concern this is…I’ve certainly had software crash on this machine before, but haven’t noticed any notable, persistent issues.


If there’s nothing for this but to chalk it up to “laptop graphics be weird sometimes, yo” that’s fine; the game runs great for me otherwise, so it’s not a major problem for me. This instance was just so easily reproduceable on my end, and so clearly caused by this one piece of scenery, that I thought it might be a specific bug with the slug grinder asset rather than general graphics weirdness.

Damn…

The reason I ask this is that, on laptop especially, things can thermal throttle to maintain temp - and this can cause decreased performance… Obviously you are experiencing some issue in this map itself but if your system is working its arse off before you get here then it may just be that this map in particular is the last straw that broke the camels back so to speak…

It just has a list of the most recent errors… some are safe to ignore, others need to be checked… usually its simple, like resetting of a cache or installing a new driver or app update. other times it can point to something more serious like a memory problem etc.

DtsApo4Service.exe points to a problem with the DTS Sound System
StoreAgentScanForUpdatesFailure0 points to a problem with the Microsoft store updating
MicrosoftEdgeUpdate.exe - Seems to be a problem with Edge updating itself…
brave.exe refers to the brave browser… with a potential memory issue RADAR_PRE_LEAK_64
Last Epoch.exe is there is another RADAR_PRE_LEAK_64 which is expected of the beta state its in…

As I mentioned, laptops dont play the same as desktop components so its very hard to figure them out… I am fairly certain that as the game gets closer to maturity/launch, these kinds of things will get dealt with but there will likely always be strange anomolies with individual setups & laptop manufacturers… You are definitely not the only person using a laptop that gets weird issues…

Sure the devs will see this and add it to their list of things to check…
