Vaethyr modpack is slow
Hello, I'm playing on the single player version of the Vaethyr modpack but despite my very good PC I have a lot of latency in game constantly.because of this, my game is totally unplayable and I'm running at around 40 fps.
can you tell me if there's a way to fix this so that the game runs more smoothly and if there's one or more mods causing it
I'd also like to add that the "frame skip" option is disabled.
here's some info on my setup and the Modpack link
GPU : AMD Radeon RX 7700 XT
CPU : Radeon 760M Graphics
RAM : 32go
VRAM : 12go
Tmoloader version : 2025.5.3.0
Game version :
1.4.4.9

Something weird happening in your game? Need to skip loading mods? Can't load a world or player? Do the following before asking for more help: https://cdn.discordapp.com/attachments/466247288331829249/481464717043564554/Untitled_Diagram1.png
Not really, its just a ton of mods slopped together, start disabling ones you dont like

There is no magic performance fix we can give you.
But I have []GB of RAM!!
Having a large amount of memory will not magically make the game run faster, much like having a bigger trunk wont magically make your car drive faster. TModLoader will use as much memory as it needs from your system already, you cannot and would have no benefit to 'using more RAM', much like filling your trunk with random junk wont make your car go faster.
But the CPU/GPU usage is only []%!!
Much like memory, the game will use as much processing power as it needs. Ultimately the majority of the game is single threaded with a few exceptions, and as such is usually limited by single core clock speed.
But why is it not multithreaded?!?!
Multithreading isn't a universal cure-all nor is it simple to handle. The game relies on consistent execution order to calculate things, and often the cost of lock contention, or threads waiting on others for sensitive memory, can exceed the cost of simply running everything sequentially on one thread. A full re-write of the game designed with thread safety in mind would be needed, and the gains would likely be less than expected.
But I have a GTX5090 giga super mega card!!
While having a powerful graphics card can help a little, Terraria is still largely considered a CPU bound game. Additionally, the advancements in newer cards are more focused on features such as 3D raytracing cores and tensor cores for processing things like global illumination and frame generation AI models, which wont help.
So what can I even do?!?!
The only guaranteed way to improve your performance is to use less mods, ultimately no hardware will make up for poorly made mods! Most mods are made by hobbyists and novices with limited time/knowledge.
