I’m having the same problem. Not just at my but also in the proximity of other bases. But for me it’s not so much frame loss, my video actually freezes up for a few seconds(but my chat keeps moving forward). Haven’t been able to isolate a cause for it. They’re not even big bases, no land claim spam, not a lot of exterior buildings and placeables just average size pvp bases. The only common factor is the DLC , it only happens with the brick based bases, it doesn’t happen at the black ice bases. Also, I notice vaults will not render until I am right up on them or passed them.
