Not that I'm aware of.
The Res you mentioned 2560 x 1080p (21:9) 60 fps was added and finally almost 0 skipped frames using 2K 21:9 or lower in 60 fps.
Unfortunately still frame skipping/stuttering image in 2K 16:9.
After further tests i'm still not quite sure if i'll stick with the 2K 21:9 60 or go with the 30 fps since 60 fps produce a more "pixelated" image and at night it's much dimmer compared to 30 fps.
But at least now the 60 fps option is usable without getting headaches watching the footage.
Another thing i noticed is that i don't have corrupted/broken/damaged files anymore.
To be honest i don't have a clue what's different now.
Maybe it's the new firmware but maybe it's due to the fact that i low level formatted the card once and since i always use EaseUS Partition Manager to format the card every time after using it in my PC to transfer the files.
All in all i'm pretty happy about it.
Would appreciate if more users would share their experiences with the new FW.
One last thing,
@exciter ,what is FW 1.6TST? Is that a modded one? How does it compare to the 1.5 or even 1.4?
Have a nice evening, everyone.
