How to fix lag?

[Zephyr]

title, i want to get back into playing this game but it lags all the time.
i've reduced all the settings to low or off but it still performs poorly.

how can i fix this?

Try deleting renderer_settings.xml which is located in C:\Users\YourUsername\AppData\Local\PAYDAY 2.

1) Set the game to Windows XP compatibility mode.
2) Set Streaming Chunk to 1024
3) Make sure nothing is lagging in the background (thx for nothing, Steam Chat)

When was the last time you played?
The game did become heavier

I changed a bunch of stuff in game to little avail (I'm CPU-bound, and in-game options only really let you change GPU performance), but mods have helped me greatly. Check out these to increase your performance without affecting the game:

BLT mods folder:

Adaptive Streaming Chunk KB: https://www.reddit.com/r/paydaytheheist/comments/5lr04o/solution_fps_drop_when_aiming_down_sights/
This mod changes your streaming KB based on whether you're in lobby or in game. It's a workaround for an ADS stutter, but I found it helped smooth the framerate when moving to new areas on big maps. Load fast when joining, and get the performance of low streaming KB while in-game. Reddit link to google drive given because the original mod was on the now-defunct paydaymods server.

No Prints: https://modworkshop.net/mod/21549
This mod disables a lot of debug logging for the game. Though they can be useful, OVK spams these chats with a ton of stuff. If you're going to download anything here, this should be what you get. Easily went +10 to my average framerate.

Performance Comes First: https://modworkshop.net/mod/24706
If your framerate is below a certain value (customizable) then this mod reduces certain calls to things like animations. It doesn't destroy the look of the game, but cop movements might look a little stuttery (they move every couple of frames instead of immediately). Helped tangibly but not as much as the above.

mod_overrides folder:

LemonCat MacroPack Smoke: https://modworkshop.net/mod/15173
The default texture size for smokes used to kill my computer, but this mod reduces it.

Winter Suit FPS Optimization: https://modworkshop.net/mod/25951
Another large file that gets reduced in quality in the name of performance. I literally cannot tell the difference.

Compressed MurkyHumvee: https://modworkshop.net/mod/25896
The White House heist is a laggy mess and it's not helped by the fact that OVK imported Unreal Engine assets into this old engine. The Murkywater humvee is a ridiculous size, so this mod reduces the texture quality. I got better frames on White House but I'm unaffected everywhere else. Considering the new heists is where the lag is most likely to happen, this helps.

Do this, nothing else.......it will clear up tearing and lag for everything and everyone.
I have a 54 inch LCD as main monitor, I fixed all issues.


Go to Settings
Go to Video
Go to Advanced

VSYNC OFF
Depth of Field ON
Chromatic Aberration OFF
Flush GPU ON
Use HQ Weapons OFF
Textures MEDIUM
Shadow MEDIUM
Anisotropic Filtering OFF
Animation Quality MEDIUM
Anti Aliasing FXAA
Ambient Occlusion AOB
Paralax Mapping ON
Corpse Limit NORMAL
Frame Rate 60
Color Grading DEFAULT
Alienware Lighjtfx OFF
DONT TOUCH FOV ADJUSTMENT
Use Acceleration Camera Effect OFF
Procedural Arm Animation ON
Streaming Chunk KB 512

I run games on 3840x2160 but I get mega screen tearing and Mouse hand-eye co-ordinational lag, so I reduced it to 2560x1440 and with the rest of the settings set at what they are, graphics are still quite amazing and tolerable.

DO NOT DO ANYTHING ELSE BUT WHAT IS DETAILED IN THIS COMMENT!
DO NOT DOWNLOAD MODS, THEY MUCKY THE GAME UP
YOU DO NOT NEED TO LOOK ANYWHERE ELSE

I FIDDLED AROUND WITH EVERY POSSIBLE AVENUE TO GIVE OVERSIGHT ON THIS ISSUE, THE CONCLUSION IS UP ABOVE!

ALWAYS RUN FRAME-RATE AT 60 and NO HIGHER!
YOU WILL ALWAYS RUN INTO PROCESSING ISSUES AND SCREEN TEARING/H-I CO-ORDINATIONAL LAG IF YOU DO NOT FOLLOW THIS!
