100% replicable frame stuttering f1 2020

Recommended Posts

Posted (edited)

1.       A detailed description of the issue. Please include any error codes here.

So I've found a way to induce frame stuttering in all modes of the game with 100% reliability and thing that this may be a reason why a lot of people experience stuttering. To note, I would describe it as "Frame time stuttering."

So in order to have this happen you may or may not need to be on PC but I am on pc. I would assume it happens on all specs of pc since I could cause the stuttering at every graphics setting.

You need to be using a Bluetooth wireless controller. (I used xbox one) and have a bluetooth adapter for your pc. Specifically I'm using a fairly cheap one off Amazon.

I think that the Force Feedback code is creating Wait on frame rendering, and if your bluetooth connection to your controller isn't high, or stable it will create the games frametime to hitch and stutter as each frame waits for force feedback data.

Why do I think this? Because I can lean back in my chair and have next to no noticeable stuttering, but if I lean forward and put my hands on my desk, giving my controller the worst connection to the bluetooth adapter, the stuttering brings the game to unplayable levels(It also makes the audio stutter and hitch, so full game engine stuttering I presume). Then I can lean back or hold the controller near my pc and suddenly my frame time returns to normal. But the ultimate tell tale is that disabling force feedback all together make my framerate higher overall and never produce stuttering, even with my hands on my desk. (I have had my controller lose connection before with my hands on my desk, in many games that I use it for. So I know the signal strength is quite weak when I do that.)

Maybe it is my cheap adapter? But I think the force feedback code for controllers should be looked at. 


2.       Platform
 Probably all of them?

3.       What version of the game you are using (Shown on the start screen in the bottom left corner of the screen) 
 1.05

4.       Game-mode? 
 All of them

5.       What are your replication numbers? Minimum test attempts are 4. Please also add EXACT replication steps for us to try too. 
 100% check wall of text. Use bluetooth with wireless controller, influence signal strength.

6.       What troubleshooting have you attempted? Please always try to attempt to fix the issue 
 There is no way to fix the issue and maintain force feedback

7.       What peripherals are you are using (gamepad, wheel make & model etc) 
 Gamepad, specifically xbox one (none elite)

8.       Any screenshots or video of the issue? If the video is long, please include a timestamp for when the issue appears.

Please post this as a full bug report as I'm interested in where this may be headed.

Not everyone will be using Bluetooth but USB 2.0 vs USB 3.0 latency could be a thing (due to difference in design spec).

The lack of consistency in frametime is something that affects the game visually and by way also impacts upon FFB feel. Hopefully this means something.

I have similar issues and play the game with multiple controllers. Xbox 360 wired controller, xbox one wired, xbox one wireless w bluetooth 4.0 adapter. So it's something else and not the wireless connection.

All of them have the same random Fps drops, random some ms screen freezes in every game mode.

He's not saying it's wireless related, it's stuff that plugs in via USB (like Bluetooth) and I tend to agree, still watching the thread. Try replicating his BT issue seeing as you have a BT controller.

Same here, I use xbox controller with bluetooth connection and stuttering with vibration on is really annoying. Once turned off, it works smoothly. However without vibration the game is no fun at all. Interestingly, stuttering is random, sometimes it works really well which made me think there should be solution. A patch or something like that could be really good.

@Flauxx does this still occur while running with a USB cable into the controller, or do you believe it is influenced by Bluetooth? Would test, but PC doesn't have Bluetooth. With using a USB cable to my controller, it seems fine.
