Rptd: [2.11.0.41] Microstutter under refresh rate with adaptive V-sync (or all the time when uncapped or using regular v-sync)

[Nushbag 8]

 I have:

• Restarted the game: yes

• Cleared the cache: yes

• Checked game integrity: yes

• Disabled custom content: yes/no

 

 Game version (2.11.0.41)

 

Whenever FPS drops below refresh rate, or if FPS is not capped using only Adaptive V-sync (Nvidia control panel doesn't work either) then there is a massive choppiness in gameplay. Additionally the issue can also be found by uncapping frame rate where the whole time there is choppiness/ microstuttering. The video below shows the issue in action. I have also attached the additional files.

 

 Steps to reproduce the issue

 

OR

1. Uncap framerate/ use framerate limiter in Nvidia control panel

2. spawn into any game mode and see the choppiness of gameplay - this was not the case at launch of update Direct hit (FPS drops were present but not the intense choppiness)

1. Start any gamemode (most prevalent in Air RB due to previous reports of FPS issues)

2. Spawn in and get FPS drops, move camera around when in cockpit for best results and notice the choppiness.

Can you please update your NVIDIA driver and retest.

Sorry for the late update, I have updated my Nvidia driver and the issue is still present at top tier air RB (along with random driver crashes - which I think has to do with bitdefender as others have realized on the forums). On ground battles random small stutters do exist however generally they are all gone. The exception is Hurtgen Forest ground RB map where the game isn't smooth at all despite still running at high FPS.

 

 

I will update this post with new Clog files throughout the week as I don't remember which ones had the issues within them. 

[KnightoftheAbyss 3,385]

Yes.  There is a known issue with Bit Defender.  Please contact Bit Defender Support(and given some of the responses by players to similar - good luck with that).  Bit Defender (and Vipre, which uses part of the BD engine) are impacted by this issue.   NO OTHER AV product is similarly impacted.  The only know work around is to remove BD and/or use another AV product.
