Mouse Sensitivity | Same Aim - Different Game

You might not be aware if you have this issue so read on.

If you are using HDMI for your monitor, it is highly probable that your graphic cards recognizes your monitor as an HDTV. In that case, your output signal is set as limited range (15-235 RGB values) instead of the full color depth of 0-255 RGB values. So you basically get poor contrasts and narrower color range.

A quick way to see if you are affected is to set your monitor to "limited range/ low black level/ or something similar". If contrast and picture quality seems to be better, you are affected. Now turn this monitor setting back to normal and proceed with the following fix.

Fixing HDMI colour output

I own an nvidia and I tried the first 3 solutions. First one didn't work. Second one worked but it throws the colors a bit off. The third one worked perfectly.

God BF4 is gorgeous now!

Edit : Forgot about a nice web based utility I found in the process for screen calibration. Its a lot more complete than the one provided by Nvidia/AMD.

Much colors !
Many contrast !

Here is a tool that helped me finding the cause of my stuttering and audio glitches.

Latency Monitor : Fix stuttering and audio glitch

More info

Read those links to familiarise yourself with the tool, what it shows, and what those ISR, DSP and pagefault all means.

Basically, you'r pc has to share its CPU time to a lot of code. Be it programs, processes, drivers, etc... (No, BF4 is not the only thing running inside that box). From time to time, the scheduler tell you'r CPU too stop its current duty (be it BF4) to run other processes. On top of those scheduled tasks comes some hardware triggered interrupts that instantly stops CPU duty to execute time sensitive driver code. Those are called Interrupt Service Routines (ISR). If somethnig is wrong in those routines, it can take much longer to execute and cause stuttering.

This tool is very useful because it can tell you how much time you'r computer waste on ISR but also pinpoint exactly wich driver is causing this. Most of the time, updating the driver or disabling it will fix an high ISR time (also thru for high DSPs and pagefault).

In my case I found that an unused network driver and a USB hub driver was causing high ISPs and my mouse driver was causing high pagefault time. Disabling the first one and re-installing the other ones fixed it. I noticed less stuttering in BF4 since.

Much smooth !
Many fluid !

Good info and tool

I'm running a r9 270x with the latest driver where has the mantle option gone ? I know where it used to be is it even an option anymore ?

There are many reasons you would not want to run BF4 with the Mantle renderer on the 270x, chief among them very bad stuttering due to a memory leak caused by poor implementation of the code in the game, combined with a too-small memory pool (3GB is recommended for BF4's Mantle renderer)

If you insist on using Mantle, make sure BF4 is being run through the 64-bit executable, and your OS is also 64-bit. If both of those conditions have been met, then you must have somehow regressed your drivers somewhere because those are the only three conditions that need to be met for the option to show up.

Edit: I need to add a disclaimer. My previous card was an HD 7870, the same GPU as the 270x. When I ran Mantle on that card, the memory leak issue was horrendous. My current GPU is the brand new R9 285, with the newest Mantle engine and a super efficient memory interface. Under my 285 in Mantle, Ultra texture settings cause the same memory leak issue that I had on the 7870. Downgrading from Ultra to High lowered the VRAM usage significantly and removed the leak issue, and actually makes the game run significantly better than DX11. If you want to try Mantle on your 270x, do what I did and lower the texture setting to High (even though on DX11 you can handle Ultra just fine).

Yeah I'm running in 32 bit so that must be the reason all the rest is the same as you assuming you're running the latest 14.12 driver.

I'm considering updating my os which is currently win 7 but 10 is just around the corner so I don't know if going to 8.1 would be worth it att.

I've had this problem a lot lately:



Basically I can play the game fine up to a point where i get kicked from a full server. If I then try to reconnect to any server, the game start only to display loading animation (without the image and it doens't load anything) and then it crash with this error after maybe 20 seconds. The issue persists for what seem to be usually 1 or 2 hours long.

I've tried several things: restarting router and modem, port forwarding, restarting computer, repairing the game etc.... nothing seems to work.

Anybody got any clue?

Yep I get it also, I reboot both my modem and pc most of the time it works but not always and like you I wait awhile and alls good again. Whats weird is it may happen several times a day and then go a week or two with no problems.

Why is the server crashing so often?
