Skytextures, (clouds moving and changing), brightness etc. update in sequence, insted of it happening smoothly as it did before. This causes rapid movement in the coulds, changes in brightness, they kind of "jolt" in to new parameters. When this happens, there is a loss of a frame or two. This is online only bug. same vmods offine are smooth as silk. This has been confirmed by others in discord. Makes online sessions very unpleasent experience. Thanks.
