Massive Performance Issues - Vulkan and DX11

[purecinn]

I've been having issues with my game since the Old Gods, New Blood updates started. At first when running my game with DX11 it would hitch really bad occasionally during matches, and crashes were frequent. I read in a thread to try switching to Vulkan shaders, which helped my performance immensely. However when Venator released after playing the game for a bit, my game will get lower and lower fps until i reset it. Sometimes the FPS dips into the single digits making the game completely unplayable. I've tried switching back to DX11, and it runs great, but randomly will hard crash my PC while using it as my renderer. No matter what option I choose I'm stuck with an awful performance with this game. It's a shame as well because I don't have enough time before my game starts chugging to play an actual match of Deadlock, and am stuck to about 1 round of street brawl before I have to completely reset my game. I miss playing the main mode a lot and even just miss not having to completely relaunch every 10-15 minutes. Would love if performance could be looked into as I've seen plenty of threads complaining about similar/the same issues with no solutions that work for me in sight.

Try this, worked wonders for me.

Good evening,
Enabling mod support on a 9070/32GB DDR4/5600X system via the guide (https://deadlocker.net/install-guide#manually) here. Upon loading into the game I immediately noticed that I was averaging 160FPS instead of my usual ~90 and this is sustained into match. Massive performance uplift across the board - no idea why. Thought it was worth bringing up here!

I think doing this did make my game run a little better. The frame rate never became completely unplayable but it did dip low enough to make it way harder to play well. Thank you for the suggestion though, I'm glad it works for others!

Hey, I think I struggeled with the same issues. Here my Post, maybe this helps: https://forums.playdeadlock.com/threads/fixed-insane-performance-issues.110553/

Once again these steps have marginally improved performance but after a bit of playing (maybe 15-20 minutes) frame rate is tanking. I think it's just game optimization issues. Thank you for the recommendations though and hopefully this helps others!

Hi,

Can you take a PerfView trace to help us isolate the issue? Instructions for taking a PerfView capture can be found on the wiki: https://developer.valvesoftware.com/wiki/PerfView#Preparing_to_Trace . Make sure to follow these steps exactly.

Once you have a .zip file, you can DM it to me here on the forums. Please also mention what OS, CPU, and GPU you are using.

Sad, that worked for me but its 100% an issue game sided. I never had to do anything on any games I play... I hope they fix it.

Apologies for the late response, I've sent you a DM.

I’m having the same issue. Everything started after that major update with the map changes. I play fine for the first 20-25 minutes with 80-120 FPS, but over time it drops to 40-80. The stutters are really noticeable, and it's impossible to play in teamfights with only 40-50 FPS. Everything was fine before the update. I didn't even use configs or GPU tweaks. But since then, I’ve tried everything and still have no idea what the problem is.
