Due to numerous reports of stuttering during races from PC users, we’ve collated some of the various tips from the community to help troubleshoot the issue and work out where the problem lies. If you can’t find a solution from the list below, then please provide us with as much info as you can and we’ll see if we can offer anymore help. Remember to post your basic system specs and send through your dxdiag and hardware_settings file to us to help us build up a picture of what is happening. If we can identify specific issues then we will likely split these off into separate threads to focus on that issue.
For anyone experiencing stuttering in the front end, replays or online sessions only, please search our technical support forum for previous reports of the issue and post a new issue if needed. All information on posting new issues, or providing additional information to help track down issues can be found here.
Confirm when the issue occurs
If the problem you have always occurs at a certain section of track, or when a specific thing happens in the game then this should be logged as a new support thread, with as much information provided as possible so that we can replicate the problem in our test lab. If the issue occurs all of the time, or at random points during play then please work through the suggestions below and see if these help to locate the source of the problem.
Check the PC minimum specifications
The intention of the PC minimum specifications is to provide gameplay greater than 30fps on the lowest graphical settings under normal Windows conditions. If your hardware fails to meet these minimum specifications then there is a chance that you will experience performance issues when playing the game. Unfortunately, we are unable to offer additional support for players whose PC’s do not meet the minimum requirements The minimum PC specifications can be found here.
Update your drivers
Please ensure that all key system drivers are up-to-date, including your graphics card and sound card drivers. This is the most common source of issues, so please double-check these. We would recommend doing a clean install of the graphics drivers – check NVidia and AMD websites for details on how to do this.
Validate your Steam Files
Our next most common cause of this issue is with the Steam cache becoming corrupt, particularly after a patch. Please validate your Steam files and see if this helps with your issue.
Lower your graphics settings
Various issues can be caused by having the graphics settings set incorrectly. This can either be that the settings are too high generally and your system can’t cope with them, or there are specific settings are not playing well with your system. Try lowering your graphics settings to the minimum settings and see if this has any affect on the frame drops that you are seeing. If the problem is no longer seen at this setting, then try increasing the settings one-by-one until you find a good balance of quality vs. performance, or until you identify a specific setting that is causing problems. If there is a specific setting causing an issue then please let us know which this is in the thread below and be sure to tell us your system specs too. It may be necessary to send through your dxdiag and hardware settings to allow us to investigate this further - see instructions on how to do this here.
Increase your graphics settings
It sounds counter-intuitive, but sometimes raising the graphics settings can shift the bottleneck on your system which could be the cause of the stalls you are seeing. Try increasing the gfx settings or resolution. It will likely result in a lower frame rate, but may alleviate stalls.
Try Fullscreen and Windowed Mode
There have been reports of frame rate being better / worse in either fullscreen or windowed mode. To see if this has an effect on your experience, please try adjusting the Display setting in the Graphics -> Video Mode menu to “Fullscreen” and running the game for a while, and then set this to “Windowed” mode and run the game for a while and see if this has any effect on the frame stall issue. You may also want to try “Windowed (fullscreen)” mode too. If you notice any significant change in the frame stall problem using the different modes then please let us know.
Enable / Disable Game DVR
Game DVR comes with Windows 10 and there have been anecdotal reports of it both improving stuttering, and also of it being the cause of stuttering. To open the Game DVR menu press WindowsKey + G when the game is running. Scroll to the Game Mode setting to the right and change the setting to see if this makes a difference to the frame stalls. It is expected that enabling Game Mode will improve performance on lower-end PCs, or those with lots of other programs running in the background, but it may end up exacerbating stalls due to excessive load on the system.
Disable Trigger Rumble on Wireless Xbox One Controller
There have been reports of micro stutters caused by using a wireless Xbox One controller with the trigger rumble feature enabled. Try disabling this and see if the issue goes away. To do this, enter the Options menu and select Settings -> Controls, Vibrations & Force Feeback -> Trigger Rumble and set this option to “Off”.
Disable conflicting software
Some third-party software has been known to conflict with the game when running at the same time. This may include performance and profiling software, streaming software and video capture applications. Please try running the game with these disabled to see if this affects the issue that you are having. If you notice any specific software conflicts then please let us know the details in the thread below and we will investigate further.
Disable conflicting hardware
Some peripherals have been known to cause some conflicts with the game in the past. To ensure that this isn’t the case for you, please disconnect any non-essential hardware from your PC (e.g. just keep mouse, keyboard and monitor connected) and run the game again to see if that makes a difference. If so, then add your other devices back in one at a time and let us know which one is causing the issue to occur.
Stop Windows Update
There have been reports of Windows Updates starting in the background while the game is running. This can affect the performance of the CPU and your disk access times which can result in stuttering. If you notice that this is running when you are seeing frame stalls then either wait and let your Windows Updates complete before resuming play, or stop the Windows Updates manually and see if this resolves the issue.
Limit the frame rate
Capping the framerate may give the PC a little extra headroom to cope with the demand thrown at it, or for moments where the hardware is struggling to feed the graphics card sufficiently. The game now has an in-game option to allow you to do this (in Graphics Options->Video Mode). Alternatively, AMD CATALYST drivers have support in the FRTC utility to limit frame rate, or for NVidia, there are a range of third-party apps that offer this functionality. Configure the game, or external program, to cap the frame rate to a lower value than your system would normally handle at the current graphics settings and then check if this affects the frame stall issue.
If this resolves the frame stalls then you may want to determine if a specific hardware limitation is causing this issue. This is generally beyond the scope of our own forums, but this set of steps may allow a user to identify if specific issues with the graphics card or power supply are at play here:
Some stuttering was known to be caused by texture streaming, where the game is struggling to bring in the required textures quickly enough. This issue is more prevalent when the game is installed on mechanical drives. Recent fixes (v1.07) should have resolved most texture streaming problems, but you can double-check whether texture streaming is affecting this issue for you by manually disabling texture streaming using the following steps:
<texture_streaming sizeInMiB="0" />
Test Gysnc and Freesync
Some instances of stuttering and frame drop may be the result of certain monitor configurations. If both your graphics card and monitor are compatible with either Gysnc or Freesync then try the following:
If your GPU and monitor are capable of G-Sync try turning it on by accessing “Set up G-Sync” in the Nvidia control panel, select enable G-Sync, and click apply
If your GPU and monitor are capable of FreeSync try turning it on by opening the Radeon Settings app from your desktop, selecting “Display”, ensuring the “AMD FreeSync” option is set to “ON”, and closing Radeon Settings.
Please note some users recommend capping the frame rate just under your gsync/freesync rate to improve input lag whilst benefitting from the improved update rate.
Set Your Power Settings to Max
Ensure that your graphics card is set to use maximum performance. For NVidia cards, open up the NVidia Control Panel, select 3D Settings -> Manage 3D Settings, scroll down the list to the Power Management Mode setting and select "Optimal Power".
