HW resourses vs framerate

[Kurt]

Hi.

Over the last couple of days I have tested PSX on a vide range of hardware ranging from a puny centrino duo@1,83GHz with 2GB Ram (Lenovo T60P laptop with 1600x1200 display) to a Quadcore 3GHz+ I7 system with SSD, 8GB Ram and a huge ATI GFX card

I am wondering why the fast 4Core(8 threads) machine is not always running at 68FPS when flying PSX, - with system monitor showing slumbering CPU with one (logic) core half utilized and another around 20% on a second logical core. The remaining cores are idle. There is no activity on the SSD. All apps like Dropbox are stopped not to influence PSX

I suppose it is the GFX card that must be the bottleneck here or perhaps PSX is coded in a way that it is impossible to reach MAX fps at all times. If that is the case I will experiment with different setups in that respect.

It would be nice to be clear on this as I then can stop or continue my OCD for max FPS  :mrgreen:

Thank you in advance

Stop your OCD.

Just fly the airplane   :mrgreen:

Dear Kurt,

did PSX run on your laptop with 2G RAM? How was the frame rate?
Thank you,

Aldo

Hi Aldo, - will check different scenarios again tomorrow and report back

Hi Aldo, - sorry for the delay, - had to reinstall Win 7 on the old IBM T60p and here are the results for IBM T60p, 2,0 GHz CoreDuo, 2Gb Ram wit ATI Fire GL GfX running at 1680x1050:

All "measured" during "demo loop.situ"

General observation in this config is that outside view ruins the framerate, - it goes below 10 fps when outside view is visible. That is probably due to only 2GB Ram..

If outside view is disabled it runs at 25-72 FPS depending on layout. Even with all MFD's visible it runs at 40 FPS+. (when setup as a client it runs 72 FPS SOLID, - as right now when looking Pierre over his shoulder)

If no MFD displays are visible it runs 72 FPS SOLID even with audio on and with moving throttles in view.

Impressive I must say !!

Hi Kurt.

Thank you so much for your time spent to answer my question.
It is amazing how much framerate is absorbed by the outside view!
So, I have to replace my old laptop with a newer one!
Have a nice Sunday,

Aldo
