Playing on a custom FiveM server with a bunch of assets, especially unoptimized ones, will do that to ya. Your best bet is to shut down all unnecessary applications on your PC when playing in hopes that that’d be enough free resources for your CPU.
update: i tried ran the pc im resolution 800x600 (adjusted it in advance graphic) and i got avg fps 80, but you know… dont go for it, but my cpu usage still 100%, i guess it because of the people in the server ( 100+) players. so thats why my cpu is 100%. will try to update later, im in planning to upgarde my ram to 2x8gb or maybe go for processor that got 8threads. what do you guys think?
TBH you just need a general upgrade; 8 GBs of RAM is definitely very little by modern-day standards, and the CPU is barely good enough as well. See if you can upgrade all of that simultaneously, should be a good boost to your gaming experience lol
