My fps is annoying. the game freezing every 0.5 seconds for 3 seconds and my pc system is very good; Processor Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz, 1992 Mhz, 4 Core(s), 8 Logical Processor(s), windows 10 x64-based PC, physical memory 8GB, and a lot more good stuff. its handling awesome on best graphics gta v which is very good, aand I have 49 mods installed, without optifine, and I just don't get it. without mods its working very good. can someone help me with that?
The quality of how the mods are coded is probably more important than how many mods you have. It only takes one poorly coded mod to bring even the best system to its knees. You might want to check your logs for anything out of the ordinary. Keep in mind though, that Minecraft uses OpenGL, and performance will depend on how well it's supported with your hardware. It probably doesn't help that Minecraft itself prior to 1.13 has some serious performance bottlenecks largely due to using LWJGL 2.9.x, which itself has a lot of legacy code supporting as far back as Windows 95.
