Why does the emulator lag?
#1
I don't understand why the emulator should lag on my computer. Maybe I had done something wrong while configuring it.

My computer specs are as follows:
HP Pavilion
Intel [R]
Pentium [R] D CPU 3.20GHZ
3.00 GB of RAM
288 GB of ROM 50% used
Video Card: Nvidia GeForce 8400 GS

I hope someone can help me.
Thank you

By lag I mean it runs extremely slow, at the best of times it will be 30 FPS, but usually its 15-20 FPS.

don't expect good speed
both cpu and GPU is weak for running pcsx2
on such 3d games it's indeed may run very slow
2d games is near-fair like Harvest moonWackoTH,MVC2 and any ATLUS games
Main PC1:i5-4670,HD7770(Active!)
Main PC2:i5-11600K,GTX1660Ti(Active!)
PCSX2 Discord server IGN:smartstrike
PCSX2 version uses:Custom compiled build 1.7.0 64-bit(to be update regularly)

Oh alright, I thought maybe I had made a mistake while configuring it. What kind of specs would be good to run a game at about 40 FPS?

Just from those specs I can tell you to tick the "native" checkbox in GSdx's settings.

The recommended specs for pcsx2 are a core 2 duo 3.2Ghz cpu with a 8600gt graphics card (9600gt/9800gt if you want to run higher than native resolution) or their AMD similar parts.

It's slow because your system is below the requirements both cpu and gpu wise to use PCSX2 decently
CPU: Core 2 Duo E8400 C0 @ 4.1Ghz
Mobo: ASUS P5Q Pro (2048Mhz FSB)
RAM: 8GB PC2-8500 DDR2
Video: Radeon HD 4850 512MB @ 790/1990mhz
Sound: ASUS Xonar DX, Alessandro MS-1 headphones

some games won't reach 40 fps even when using a c2d 3.ghz

It's really game-dependant
CPU : AMD Ryzen 7 3800X
Mobo : Asus PRIME B450-PLUS
GPU : NVIDIA GeForce RTX 3070
RAM : 16 Go

..And you'll want 50fps for PAL games, or 60fps for NTSC games. Everything else isn't really enjoyable much.
So yeah, depending on the game you need a core2duo 2.4Ghz (easy to run game) up to core2duo 4.5Ghz (the tough ones Tongue2 ).

Edit: And yeah, I know you cannot even buy the 4.5Ghz one (only heavy overclocking gets you there). It's the way it is, sorry Tongue2
