PUBG Performance Settings (Stutter, Low FPS & Input Lag)

There are many fps problems, input lag and stuttering that you may encounter in the PUBG game. Here are some tweaks you need to do to fix these pubg fps problems.

What is this?

This is a short collection of tweaks that I found helped my computer run PUBG better. It did not necessarily increase my FPS, but it helped with stutter and input lag which made the game much easier to play.

  • This guide is mainly for people who have a nice gaming rig that is up-to-date (or mostly up-to-date, at least) but are still having issues running the game smoothly with low input lag.
  • You can still try these tweaks on an older system to see if it helps you at all. I am using a GTX 970, an i5-7600k, 144Hz monitor, and 16GB RAM. These tweaks helped me significantly. Perhaps they can work for you as well. Especially if your system is similar to mine.


Important Note Before Starting

This game is very poorly optimized and it takes a beast computer to run at a steady 120 fps+. Don’t expect these tweaks to give you amazing performance enhancements, especially if you are on an older system or have significant bottleneck(s) in your rig.

Let’s get started.

Increase the Paging File Size

Increasing the size of your paging file, a.k.a. Virtual Memory, can reduce stuttering in PUBG. It is not currently known exactly how or why this works. This tweak reduced stuttering and input lag greatly for me.

The paging file, or Virtual Memory is a Windows feature that utilizes some of your hard disk space as “virtual memory” instead of using your physical RAM. There are various reasons and benefits of doing this. I won’t go into technical details about how exactly this works. If you want more detailed information about this, either use Google or click this link[].

However, PUBG seems to utilize RAM and the paging file in such a way that it requires a bigger paging file size than the Windows default.

Note: The paging file uses hard disk space so you must have free HDD or SSD space to dedicate to your paging file.

Here is how to increase the paging file size:
1. Go to your desktop and right-click on This PC and select Properties.

2. Click Advanced System Settings on the left column.

3. Click the Advanced Tab near the top of this window. Then, under Performance, click the Settings button. This will bring up the Performance Options window.

4. Click the Advanced tab. You will see a section that says “Virtual memory”. Click the Change… button.

5. Click the “Custom size:” radio button. Then in the boxes, type in a much bigger file size. This is what I am using, but it is an unnecessarily large size. You can go with 20000 and 30000 MB. Just make sure you have this much free space on your SSD (yes, an SSD is preferable as it is much faster than a regular HDD). Then click the Set button. Now, you must reboot your computer to apply these settings.

Change the Frame Limiter Mode

Changing the Frame Limiter mode can supposedly decrease stutter and input lag.

1. Download Nvidia Profile Inspector. Download Here[]

2. Open Nvidia Profile Inspector.

3. Select PLAYERUNKNOWN’S BATTLEGROUNDS at the top where it says “Profiles:”.

4. Browse down to the section “2 – Sync and Refresh”. Select this option:

5. Click “Apply changes”. Start your game to see if it helps.

6. You can also try this option if that one does not help:

This tweak is from Banana Gaming:

This setting reduced input lag for me, which made aiming easier. I’m not entirely sure how this works, but it seemed to help. Try both options if you want and see if they help you.

Set Affinity

The following tweak was kindly sent to me from user Ev1N -RBOK:

Ev1N -RBOK: So if you have any other meaty programs running, like OBS or something, you can “Set Affinity” in task manager and assign it to different CPU cores than the ones PUBG is using. It gave me abuot 55 more fps when I moved discord, steam, razer synapse and chrome to my last 4 cores while using only essential windows settings and PUBG on my first 4. Only really works with CPU’s with more than 4 cores though

In-Game Resolution

The following tweak was kindly sent to me from user Ev1N -RBOK:

Ev1N -RBOK: Also lowering the resolution of PUBG if your GPU is weaker than your CPU is a good one, it balances out the performance between the 2 of them
Ev1N -RBOK: 1600×900 look very close to 1920×1080 yet it runs a hell of a lot smoother

PUBG Best In-Game Graphics Settings

Here is how to set your graphics settings in PUBG.

If you’re hoping to tweak the individual settings to better tune performance, I did some testing to see how much each setting affects framerates using the ultra preset as the baseline. I then dropped each setting down to the minimum (very low) setting and to measure the impact.

  • Screen Scale: The range is 70-120, and this represents undersampling/oversampling of the image. It’s like tweaking your resolution by small amounts, but I mostly recommend leaving this at the default 100 setting.
  • Anti-Aliasing: Surprisingly not a major factor, but this is because Unreal Engine requires the use of post-processing techniques to do AA. If you want better AA, you could set screen scale to 120 to get a moderate form of super-sampling. Going from ultra quality AA to very low quality AA had a negligible impact on performance.
  • Post-Processing: A generic label for a whole bunch of stuff that can be done after rendering is complete. This has a relatively large impact on performance—going from ultra to very low improved framerates by 15 percent.
  • Shadows: This setting affects ambient occlusion and other forms of shadow rendering, and going from ultra to very low improved performance by just over 16 percent.
  • Texture: Only a minor impact on performance, provided you have enough VRAM. Dropping from ultra to very low increased framerates by 5 percent.
  • Effects: This setting relates to things like explosions, among other elements. Interestingly, in earlier testing it didn’t appear to affect performance much, but now it’s the single most demanding setting in the game. Dropping to very low improves performance by up to 25 percent.
  • Foliage: Given all the trees and grass, you might expect this to have a larger impact on performance, but I only measured a 2 percent (1 fps) difference after setting it to very low.
  • View Distance: This appears to have a greater impact on CPU performance than on graphics performance, so if your CPU is up to snuff you can safely set it to ultra. Even on a Core i3 system, dropping to very low only made a 3 percent difference in framerates.
  • Motion Blur: There’s a reason this is off by default, right? Spotting enemies while moving around is more difficult with motion blur enabled. But if you like the effect, turning it on causes about a 2 percent drop in framerates.
