Why does the game run so badly for me?

[Slimurgical (Stormy)]

I have parallax to 0, all effects turned to their lowest settings, windowed mode maximized does nothing, geforce experience won't offer any help with it because Nvidia doesn't make good software that works exactly as well as it ought to. With Frame Skipping On, I get 1-13 FPS when playing online (170 MB/s Download, 15 MB/s Upload) or anywhere from 12-56 FPS playing singleplayer.

Here are my computer specs:

Operating System
Windows 7 Home Premium 64-bit SP1
CPU
AMD A10-5800K 70 °C
Trinity 32nm Technology
RAM
24.0GB Dual-Channel DDR3 @ 798MHz (11-11-11-28)

ASRock FM2A85X Extreme4-M (CPUSocket) 38 °C
Graphics

1023MB NVIDIA GeForce GT 730 (ZOTAC International) 46 °C
Storage
931GB Western Digital WDC WD10 EZEX-75ZF5A0 SATA Disk Device (SATA ) 33 °C
1863GB Seagate ST2000DM 008-2FR102 SATA Disk Device (SATA (SSD)) 37 °C
Optical Drives
HL-DT-ST DVDRAM GH24NS95 SATA CdRom Device

Terraria and Tmodloader is on the SSD

My modlist can be found at the following link: https://steamcommunity.com/sharedfiles/filedetails/?id=2856472491

Can anyone tell me what the problem is here so I know what I need to upgrade? When a player with end-game gear simply exists near me, I end up lagging so hard I have to spam-click just to access my settings menu. Terraria only uses up 3,600,000 K of memory and usually only 25% of my CPU and 30% of my GPU. I put dotnet.exe at Above Average priority and no change.

I'd like to play this game at a half-decent framerate, any resources anyone know of to point to my problem? Any help would be highly appreciated!

Did you try to lower your resolution?

[emmmmm]

buy a new computer will solve any question.

I could only lower it to 1024x768 at the lowest but the resolution makes no difference.

People who read can know that's one of the ideas behind this post, so name some suggestions for parts I can get that wouldnt' have this problem.

Because my lag issue does not exist in Vanilla Terraria in any respect, it runs perfectly. From what I can tell ,the problem may be either unoptimized code in Tmodloader, or in a mod, or Calamity itself and some other mods explicitly require greater resources to run at a rate one can only be proud of.
I plan to test modless tmodloader to try and find he issue and also deactivating mods one at a time tomorrow

A small suggestion, I don't know if this is a reasonable option, but you can try to run the game through OpenGL or Vulkan
To do this, in the launch options, specify /gldevice:OpenGL or /gldevice:Vulkan

[Neonivek]

One good strategy is to turn on and off mods to see which one is causing the problem (assuming it isn't simply the bulk of mods or a conflict between two mods).

Your specs are terrible. That is the harsh truth.

[JackieTheDemon]

Not sure why you included temperatures lol. You're gonna want to get a new computer, in order for us to suggest parts, we would need a budget.

[Doom Sayer]

While your specs are terrible it doesn't merrit the performance you claim ingame. I dont have a clue why you would have such issues and I dont have specs that bad to test. Clearly there is some issue outside pc being bad.

I mean you are running modded i dont know how that modlist breaks optimization since I have only played vanilla style modded.

On upgrading you would need to give country and budget and would you would use it for, the usual things (specific games u play or would want to). In the US at least its both a decent time to buy and a decent time to delay due to new gpu and cpu releases approaching combined with lower parts costs this year.

Like other people who replied how is it justifiable to say its pc issue? It can boot ingame any modern AAA game from what i saw on yt and since Terraria is low spec compared to a 2d game like noita lag of that level is not to be expected.
