Viper V4 Pro LOD issues?

Just recently got Viper V4 Pro. Seen people talk about this on reddit and hope if anybody could shed some light on the matter. The LOD feels high for me on Viper V4 Pro when using low LOD settings, especially in comparison to Viper V3 Pro. I am able to perform tracking motions by hovering the mouse above my pad without the skates touching.

 

Never tested the mouse with stock/base FW. Saw there was a FW update on launch and figure it had to do with their web based synapse, so just performed the FW update right away.

 

Also I think there’s a distinct jitter timing at 8khz when performing swipe test on MouseTester that’s not present on Viper V3 Pro on 8khz. Wonder if anybody could possible educate me on the matter as well.

 

Thank You for taking the time to read this post. Hope you all have a wonderful one

I’ve noticed this. I have both Viper V3 Pro and the new Viper V4 Pro. I think either the FW or Synapse is bugged. Low LOD on both models are NOT the same. On the V4, the low LOD feels like the Viper V3’s Medium. 

 

I have both connected right now and they are obviously very different. Exact same feet and glass mousepad (CR005).

    Okay cool. By chance do you use 8khz? or your system work okay with 8khz? Cause on VV4Pro, there’s this constant jitter timing outlier present at 8khz that’s not present with Viper V3 Pro. 4khz on Viper V4 Pro looks perfectly fine. It’s just there on the 8khz setting

     

    I was using MouseTester just performing a swipe. Would figure the graph look clean/sharp at 8khz with the new FrameSync tech in it

     

    EDIT: I just submitted a ticket to support. Hopefully there’ll be some news on it
