FPS
Posted: Thu Aug 16, 2012 11:03 pmThis may have been answered elsewhere and I have searched. I was using MSI afterburner and HWinfo64 for monitor my GPU and CPU load as I was playing and I noticed that my CPU and GPU were using only around 50% load per which did not make any sense to me so I started rereading the hundreds if not thousands of posts around the web and noticed a very large number of high end, multi core systems with nice GPU's having problems with no real answers given. My first clue was upon starting another game (Red-faction Guerrilla) that afterburner told me I was using DX10 but that slot was empty on railworks, so I exited and had HWinfo show me the not just per core loads but the current MHz of each core and guess what? any game that popped up as a DX or OpenGL program the CPU would bump to 2.77GHz per core but in Railworks? 1.5Ghz. So I decided to see if forcing the power save feature to run 100% CPU at ALL times and my FPS went from 10-14fps to 30-35fps constant. Apparently Railworks 2012 does not kick the Power save feature off on all CPU's (I would assume that newer CPU's with more extreme save features would be more impacted) and if the CPU can't process Physx fast enough on the allocated core the core that is controlling the GPU cant send instructions fast enough and hence the GPU cant render the frames at a decent rate. also seems to me to indicate why the CPU and GPU show low overall usage, kind of a domino affect.
Most of this is just conjecture and wild guesses on my part but one thing I do know is that my CORE I7 920 and GTX 260, 216core, 896mb were not getting full use until I set manual CPU power save off. now core #1 shows 90-100% use at all times and the rest of the cores fluctuate between 30-40% with the GPU at around 60%
If this has been said and discussed before mods please delete but I wished to share a possible solution that I have yet to read about and I have read HUGE numbers of posts on performance problems of good equipment since purchasing this sim at the time the BIGBOY was released.
Go to control panel, Hardware and sound, Power options, select High performance and then change plan, change advanced, processor power, and set minimum to 100% and check that maximum is at 100% also. you should also set cooling to active or it will slow the CPU to keep the PC quiet. on different OS it may not have this problem but on my Win7 it did.

Most important is that this means that BigB suggestion makes the trick indeed, if the case. BTW I have a desktop. I've just recalled that Chris (from Arizona) had suggested this tip for laptops sometime ago.
