Discrete GPU to run PSX smoothly?

[GodAtum]

I have two choices. Would a discrete graphic card make a huge difference to FPS?, especially for manual landings?

1/
Core i5 5200U 2.2 GHz
8GB RAM
Intel HD Graphics 5500

2/
i5 4200H 2.8GHz
8GB RAM
NVIDIA GTX 760 6GB

My Specs are as follows for my sim if this helps?  I could have done PC2 and PC3 on a single PC with the 3 gfx cards if my monitors in the MIP were DVI as I cant find any cheap cards which support 2 x VGA monitors on the same card.  

PSX Server / IO
=========
i3 onboard graphics, single monitor
PSX locked at 72FPS with windshield view active but dusk/sunset/ shading disabled
Running a few additional apps on here
All USB IO On Here

Avionics
=====
i5 with 3 £30 gfx cards in doing Capt,Eicas,FO
72FPS Again...
FDS MCP On here too

CDUMFD
======
i3 with 3 £30 gfx cards doing CDUL,MFD,CDUR
72 FPS Again
FDS CDU On here too

Instructor
======
i3 onboard gfx
Running touchscreen instructor and CDUC
Also running vpilot, activesky,BACARS,Skype,VisTraffic etc..

P3D
===
i7 with 2 x GTX770's and Visual PSX @ 40FPS for 3 projectors

Cheers

(PS: Saw your boxes waiting for you at Steves this weekend... very exciting!)

Thanks for your specs list. I am very tempted by the new Intel NUCs, very compact. I plan to have 3 PCs running 2 displays each (CP ND/PFD & right CDU, upper EICAS & loer EICAS, FO ND/PFD & right CDU). But I dont really want to buy one and find its not powerful enough.

I also plan to have a headless server running PSX in server mode. I would RDp into this from a laptop to act as an instructor station.

Haha, did you drive up from Farnbrough then? I am very excited, like Xmas

Hi GodAtum

I'm currently testing an Intel NUC ( i3/1.8GHz/8Gb ) running the complete 'PSX works' (PSX-server/boost, SIOC, PSXseecon & CPFlight) including related OpenCockpit & CPFlight hardware and don't have much of an issue with framerates despite having a 'full' CPT Panel (including upper/lower EICAS) displayed on one screen (27") ...  OK, I'm not pegged at 72FPS but I'm not dropping much below 50FPS at any time!

So I would expect that this machine would be sufficient for what you want to achieve.

I did a quick test with just a PFD/ND & CDU setup on the two screens (22" & 8") and was very happy with the results. I expect I'll be going down the same route that you are considering - using NUCs !

Regards
Simon

Cool sounds great. What discrete GPU do they have?

[simbro]

Differs depending on the model.  Mine uses a built-in Intel HD5000

Only thing that caused a slight hiccup at the start was that graphic output is via HDMI only!  Had to locate some adapter cables before playtime!
