Theres horrendous micro-stuttering happening. Im pretty sure it has to do with the drivers and/or the RDNA3 architecture vs the client but i thought i could try my luck here. I have tested C4, Interlude, Classic and Essence clients and theres no problems with those, performance is excellent. I also tried using dxvk (dx9 to vulkan) but there was no change so im sure theres something in the client causing the problem. I ruled out the server side after trying both L2JServer's H5 and L2jMobius, micro stuttering persisted with both.
I guess i should either wait for AMD to do more driver optimisations or just forget about Epilogue and High Five if there isnt something that can be done client side about it.
