Really poor graphics performance...

Many thanks for your explanation!
In the coming days i will receive a new graphics card (GTX460 1Gb), i think it will help a lot.

Just received the new graphics card.
Same route, same activity...

Old 8600GT 256Mb: 8fps

New GTX460 1 Gb: 160fps!!!

Wow!

Interesting confirmation about where the bottleneck for Open Rails lies. Certainly for OR, high end graphics cards have a huge impact. Congrats on the new card.

It's interesting, I have had all shadows turned off in MSTS for ages. After seeing this I thought I'd give it a shot, turned all shadows on in MSTS, about 30FPS with the Columbia Falls Setout on Marias. ORTS 360 with dynamic shadows enabled, about 30FPS. Aside from no distant mountains, the main difference I saw;

Is probably brightness or gamma settings. My specs;

Hello,

I believe that more objects in Open Rails cast shadows than in MSTS.

Hello,

I believe that more objects in Open Rails cast shadows than in MSTS.

An earlier version of OR did shadow everything by default but that got changed and so now (for static objects) you have to set the show dynamic shadows flag on each individual object to have OR do a dynamic shadow for it.

As i see in openrails the shadows are displayed very far to the player. Will be the shadow LOD-ing possible? For example the shadows only needed to be displayed in a 200m circle around the camera.

I get 5/8 fps with dynamic shadows activated, pretty unusable.

Really?, that's interesting after seeing what kind of performance I've gotten out of laptop with a weak mobile version of the 7900 (Go 7950 GTX) and OpenRails with dynamic shadows enabled on a demanding route like the Feather River -
