Hello, I’m writing this to ask for help from the people here, so you can be my voice. I’m a regular PUBG player. About a year ago, I set the game to 30 FPS. After a few minutes, I went back to Unlimited FPS to avoid straining my PC. I felt a difference in the game’s fluidity at that point. I shared it with my friends, and they felt the same difference. Later, to spread the word, I made a YouTube video on https://youtu.be/ZGZP9XGci1M. There are more details here. You can check out my pinned comment. I first shared this with the community to prove it wasn’t a placebo, and indeed, this is definitely a problem. I later contacted PUBG Support with references here, including esports players, and they still haven’t taken any action. The issue is simple: set the game to 30 FPS, wait a few minutes, and then set Unlimited FPS, and the game becomes noticeably smoother. I’ve done a lot of research into why this might be happening. I assume this is due to the use of a hybrid engine, which is related to the fact that they override the Netdriver system, which uses Unreal Engine for the Visual Engine and KRAFTON Net Engine (C++) for the Network Engine. They use this instead of Unreal Engine’s own replication system. While PUBG isn’t tick-based, it operates with a server-authoritative hybrid tick system. PUBG’s hit registration differs from other Unreal Engine games. PUBG’s load has never been on the GPU, but on the CPU cores. In a 100-player server, the load is concentrated on a single core (GameThread). PUBG implemented the Task Graph System and Parallel Replication to address this. However, they still haven’t resolved this issue. On the client side (the player’s computer), there’s still a GameThread + RenderThread distinction. This is due to the GPU’s idle time, which has always caused PUBG to stutter even with high FPS. This is due to the GameThread bottleneck on the CPU. Now, in addition to the high FPS issue I’ve described here, the network engine issue is also causing a real drag on the gaming experience. I urge those with knowledge of the issue to investigate and raise awareness. There’s a major problem here, but a solution isn’t readily available.
