BeetlePSX_HW 1.8.5 Windows 10 configuration help

brand

Hi there! I'm running retroarch (retroarch and cores updated) in Windows 10 64 bit on a pretty old but still capable laptop.

Its specs:

Intel Core i7 2860qm 2,5 - 3.4 GHz (all cores)
8 GB DDR3 dual channel ram
128 GB sata3 SSD
Nvidia GT540M 1 GB (latest official drivers availble, no mods)

I can play gamecube, dolphin, N64, some Wii U, Redream at 720p at 60 pretty much stable FPS. I can also run some less demanding PS2 games and I was even able to run Worms on RPCS3. I have correctly set my Nvidia drivers to use the Nvidia GPU and not the intel integrated graphic (checked with the Nvidia built-in tool).

What I cannot do is to make my PS1 games with Beetle PSX HW run at 720p at 60 FPS.

It would be awesome if I could run them at 1080p but I don't think that my "GPU" is powerful enough, to handle both shaders and a full HD resolution. I don't even think its capale of pushing it at a 720p good looking maxed settings.

Would you be so kind to guide me through the most suitable settings?

This is what I have and it's pretty close to what I remember I was getting on my original Playsation when I was a kid:

Renderer: Hardware
Framebuffer sofware: on
Internal res: 2x
Color depth: 32bpp
Dithering: off
Texture filtering: nearest
PGXP mode: memory only
Vertex cache PGXP: on
Perspective texturing PGXP: on
Line to quad hack: default
CPU Dynarec: disabled
Dynarec code: full
Dynarec cycles DMS/GPU: 128
CPU overclock: native
Overclock GTE: off
Overclock GPU: 1x
Pal video timing overide: on

All the options that I did not mentioned were left untouched.
