Pacific Drive Performance Fix - THE REAL DEAL, NO MORE STUTTERS

[Hazania]

I discovered that shaders are the primary cause of incurable stutters in Pacific Drive. They are compiled on-demand and are not saved between sessions — which results in sporadic stutters for each shader that is compiled. The first time you use each tool, see an anomaly, get hit by a storm, or enter a unique zone; new shaders are being compiled. This is not particularly unusual for a UE title, except that these should be saved permanently within the game files so that it only happens once per shader. With this fix, your shaders are permanently cached once compiled in-game.

Simply, replace the contents of your Engine.ini file found in AppData/Local/PenDriverPro/Saved/Config/WindowsNoEditor with these settings[pastebin.com].

Reddit Links:
1. Step-by-step install/uninstall guide.
2. Before & after benchmarks.
3. Detailed explanation, and each UE4 setting used.

This fix does not reduce graphics and therefore will not raise your maximum FPS. It is intended to reduce stutters; it should increase your 1% Lows significantly and may increase your average FPS. However, u/TheHybred's Low Quality Preset helps with increasing your maximum FPS at the expense of graphics quality, if my fix is not enough.

works for me. didnt remove them completely while it builds the shaders but with some patience, it drastically reduces them.

Glad it helped! I noticed the same thing as well, however the updated solution I posted does help with that as well.

the fact this is even something that someone took the time and had the time to figure out, speaks volumes to how slow the devs have been at fixing performance issues.

the updated settings both reduced stutter on launch and some of the more general stutters i was having. i did have to delete the precache files you mentioned. no graphics or graphics settings were changed that i can notice.

Heck yea! I’m so glad to see my effort paying off. Huge thanks to u/TheHybred who spent months putting together the settings that I dissected for this fix.

i have begun to notice some minor graphical errors, minor things. such as the gas pump textures blurring, and decal paints blurry as well, or even the planning maps background. the rest of my prior statement remains true though.

Thank you so much for the effort, Hazania! I have copied the pastebin contents to Engine.ini and while the performance is vastly improved, the textures are now extremely blurry - for example, the world map is just a big unreadable smudge.

In the Video settings, texture quality is displayed as being set to Ultra. I tried changing it to High, and then back to Ultra, but it didn't help.

Could you please help me figure out what went wrong?

i believe im experiencing the same thing with the road map.

I will look into the rest of the Engine.ini contents and figure out what is the culprit, thanks for reporting this!

I think I found the culprit. I searched for the keyword "texture" in the pastebin and one of the settings looked suspicious to me:

r.Streaming.FullyLoadUsedTextures=0

After changing this setting to 1, the textures were still blurry when the garage loaded in, but they became crisp after a few seconds.

Not sure if other aspects of graphical fidelity are affected, but for now it looks fine.

Well done! Will update the pastebin now!

Let’s keep this thread going. If anyone else finds improvement from this fix please comment! Thanks!

Damn, that's some fine work right there! Thank you very much for taking the time to research this AND share the results with us.
