Question about stock Panzer campaign

[21.Gr.CT.Ludovisi]

VR user here, with 4080+Quest 2, long time player with IL2 but newbie with TC: no problems of performance with IL2 and with single mission of TC, but the first mission of stock german campaign is unplayable for me due to stuttering/low fps... any suggestion for TC settings?

Thanks

not really working, fps are low regardless graphic setting, IMHO too much tanks/objects/smokes...
