18k should still do 60FPS, but if we then factor in CPU time between each call (ie sending calls and processing objects at the same time on the one thread) the performance goes to pot.

Minecraft is a common example, practically everything client-side is done on the one thread so as you increase the draw distance it just cant maintain a good framerate despite nothing even going on in the distance and the GPU running cold. Unless you look somewhere that the distant chunks should be culled out of drawing (eg looking at the sky/ground or being in a cave).

edit; oh wait was that 18k each second or 18k each frame? If it's each frame then that's utterly stupid...

On all ultra the BOS PD scene improves by ~50% for me by changing shadow distance from ultra to its lowest setting. Odd thing is, when it was on ultra the GPU AND CPU were not seeing maximum load (~70%). On medium shadow distance GPU usage went up to 100% and CPU usage increased as well.

Distance shadows seem to be the thread holding things back, at least from my testing.

Nice catch. I didn't think to try adjusting that setting. smile.gif Now we just need other people to try this with various systems and see if there's some consistent results.

EDIT: Just tried running 1440p ultra with only shadow distance turned down to medium (everything else maxed, except motion blur off), and yeah, pretty much solid 60fps with the occasional dip into the 50's which is almost unnoticeable. Turned shadow distance up to high and it tanked down into the 40's and 30's and didn't stay at 60 very much.

So that's pretty obvious, to me, what the problem is. I'm now a very happy gamer, knowing I can enjoy the rest of the game in smoothness. No more slide show! biggrin.gif

Test this out and post up your results, folks.

Same result for me" shadow distance down to medium. GPU Usage back to 100% and 60 FPS. Finally i can enjoy this game

I run screen capture now, the CPU usage is 10-20 % higher than normal.Normaly it stays within 80 % at all time. Probably due to the screen recording. The FPS is normally in the low 30.

But what i find strange is that even with the CPU usage in the 70-80% at the start i get 60 FPS. This is what i normally use when I am not recording and the fps is 30.
To prove I am not kidding with the CPU usage, i recorded with my cell afterwards. The CPU does not exceed the 80%, but the FPS stays at a steady 30 fps.

The graphic setting have not been changed, I don't get this, anybody with an I7 having any problems?
Isn't the cache a bit different from the I5?

Probably known to all know. But did re visit my save game and the game finally runs well (at least with this issue) with Crimson 16.1.1 and the 1.3 patch:
Confirmed by others as well:

Screenshot from my PC, FPS steady at around 75 fps limited by Crimson target control:
