Bizarre fps drop in 60fps games
#1
PCSX2 runs fairly flawlessly on my system excepct for one nitpicking little thing where any game that runs at 60fps has this problem where the framerate drops and skips a bit intermittently in between about 1 minute increments and lasts for just 3 or so seconds. I have everything set to default settings with no enhancements to graphics or otherwise to keep the emulation accurate. Happens in both hardware and software modes.

PCSX2 Ver. - 1.4.0 (Latest Stable Release)

I'm using all default settings and safe presets. I play from ISO and this effects 60fps games like Sly Thevius Racoonus, Tony Hawk Pro Skater 4, Medal of Honor frontline, Maximo Ghosts to Glory, Tekken 4, Metal Gear Solid 2 Sons of Liberty, etc. There's a clear distinction between the emulation's frame rate dropping and the intermittent hanging I'm experiencing.

This is a problem with all GIT builds since sometime mid-March of last year. Stable 1.4.0 doesn't have this problem if you use GSDX OpenGL. I already reported the issue on Github, but no fix as of yet. It also seems that I'm not the only one to notice. I seriously hope they fix this before stable 1.6.0.

I still have the problem when using OpenGL in hardware or software.

EDIT: I also seem to have the same problem in the latest dev build as well.

It happens no matter what if you aren't in fullscreen. It also happens if you have a high refresh rate monitor. I have to set mine to 60 Hz or else I get stutters. Would any of these scenarios affect you?

No I use fullscreen and I have a 60hz monitor.

Do you set the GPU to Prefer MAX performance in the NVidia control panel?

^ This... I remember getting not just stutters, but straight-up slowdowns if I didn't have my GPU set to Prefer Max Performance (and I have a 1080 so it was even more bizarre for me). If you haven't already, definitely give this a shot.

Nevermind, an error. Smile
