pretty good idea is engine update because of trains no I actually seen a couple of, threads about this a lot of people think that the reason why we did the engine upgrade was because we needed the the physics for the trains in in in the end upgrade that's not true yeah that's not the case at all we are hoping to be able to like move over to the new physics engine, that unreal are working on right now but that's not tied to like engine update 426 or anything like that, but that's we are very early in that so even me mentioning that is probably like like doesn't doesn't mean anything because we haven't even started looking into that, we're still using the same physics engine we're still using physics I think we're using or which yeah and we might not change so, but it but the, the engine upgrade has nothing to do with like specifics in update five I think the engine up it was more that we saw like some improvements in the editor and directx 12 and vulcan support is better, I think that's the main reason really people that have directx 12 support because directx 12 has had like increased, performance significantly for some people so that's great yep but that's the main reason why we updated engine version I think
