Over the years, graphics have become more and more heavy to render and this ‘‘mouse input lag’’ issues became a big problem with many games and game engines. That is precisely why Quake 3 Arena, after 20 years, still offers the best ‘‘mouse feel’’ that we can find out there. And from memory, I think DOOM 2016 running with the Vulkan API is one of the only great looking shooter game that doesn’t seem to have much mouse input lag.
The mouse input lag issues have been present in games developed with Unreal Engine 4, but also with Unreal Engine 3. Unreal Tournament 2K4 also had this issue, except that at least it had a decent option to reduce input lag. FPS players have been complaining about this issue in games developed with Unreal Technologies since at least 2007 (Unreal Tournament 3). Many of us were hoping that this mouse input lag issue would finally be fixed in Unreal Engine 4, however the issue is still present. Shooter games are some of the most popular genres, it would make a lot of sense to spend a considerable of time, money and effort to make sure those games feel right when we play them.
As we can see here the following thread of Unreal Tournament Pre-Alpha, it shows that the UT dev team recognized the existence of this problem, but didn’t seem to be sure of what was causing the issue. And didn’t yet have the tech to fix it either. I heard that the Vulkan API could be available for PC later this year. not only I hope it’s true, but I also hope that it could help fix this issue.
Please Epic Games, could we fix this mouse input lag issue once and for all?
For all shooter game developers & players out there, we would greatly appreciate it.
Thank you in advance,
