IMO your overkill GPU falls asleep...

I bet your CPU and GPU are idling

Get the openhardwaremonitor.org and look what the clocks are doing when you drive.

Axel,
I couldn't get openhardwaremonitor to work (it just shows the motherboard and cpu without any indication)
So I installed psensor (less complete), indeed after a quick tour on Aindiab, although I don't have the fps drop like on the server, I get 43% usage for the gpu and 22% max for the cpu...

[Clive Loynes]

I have turned down the quality on my GTX660 to 50 percent. It had no problems at Torino last night but RACER only use 36fps.

With the problem at Ain Diab being at the same point each lap it must surely be track related.

I will give it a trial on Spa but I only get a problem when on line.

@Clive, my advise is to turn the quality as high as possible (~73%) to not let the GPU idle! Set the AA to 4x (disable intel speed step) for Win

@ Christian, yes the OHWM does not help much in linux. I use a combi of CPU-X and psensor

Main thing is the CPU running top frequency - load is not as important!

..maybe this helps in linux to keep the CPU from idling


just tested on my office PC (GT 1030 passive) full grid start at Spa67 from rear with full 60 fps

I only seem to have the options of 100% quality, 100% performance and 50/50.

Off-line I can run a full grid of AI at Spa without any problem.

Until the race on Sunday I didn't think that I had a problem!

Where do I set AA 4x?

ok, in the GPU driver you set to max quality - but in game set the detail slider to ~73%

This Ain-Diab track seems to have a problem with drawing distances...

AA = anti aliasing

[Christian Dauger]

Axel, I don't see anything with cpu x that allows to change the CPU frequency...?

I take the occasion to ask, what is the lod bias in the Gem settings?
And what are the best settings for Rasteriser?

Thanks Axel, yes I knew what AA was, just not where to set 4x but found it in the Nvidia control panel.

I had run the GPU at 100% on the GPU driver since installation and had no problems until Sunday at Ain-Diab.  I don't know what the detail bias is set to in the game but will check next time I fire up the racing PC.

But why does it only happen on-line?

Thanks again.

@Clive

online the chat + messages are running in the background what eats a lot of CPU load - this is the main problem of our version of OGL: displaying fonts
minimize message font size in the gplshift.ini!

@Christian

in mint I installed "cpupower-gui" this is what is shown in the pics above

my settings

[Clive Loynes]

So......
The chat uses CPU power even if no messages are being received and the track's draw distance issues push it over the edge when on certain parts of the track?

I don't know everything about these problems but in SRMZ there is a thread about this topic where many people wrote about it.

You can see the font/text phenomenon yourself if you change the info on the left side next to the TV in the game menu. More live text makes more jerks inTV.

when on certain parts of the track?

Is that at the end of a sector, when times are refreshed in Pribluda?

I have a weak system. Under Win7, sure I got some occasional lower-FPS at times (start of race etc)  but didn't suffer from any chat/connect/disconnect messge stutters. But I was aware of plenty of others with that issue.  I DO have the issue under Win10  (both from Win7->Win10 update,  and also with a fresh Win10 install).

At one track (possibly Nassau with 55 cars) I was sometimes getting a constant 30FPS. I got better results by switching off the latency bars.

In the Monza10K 55 race, I had bad FPS issue at the start (probably all those cars ahead to look at!).  I downloaded the lite 55 carset for Ain Diab, but not sure if it helped.

Otherwise, everyhing mostly works fine & GPU clocks do ramp up / CPU is stuck running full whack.

[Cookie]

Yes, Nassau in the original version made my PC also down to 30fps (because of VSync!) but after I installed Ginettos patch all is fine

As long as you use Win as OS, I recommend to use the openhardwaremonitor to see in the graph,
if the speed step of the CPU is switched off and the GPU frequency runs full throttle.

whenever I sit in the car the clocks go to maximum

[Clive Loynes]

OHM installed and the CPU clocks appear to be on maximum when GPL is running.  I haven't gone as far as jumping in and out of the car and then looking at the graph.

Great, now look for the GPU clocks as well

CPU clock goes up when a gplxx.exe is running

GPU clocks need stimulation by high quality + AA settings - but too high can be contraproductive...

That seems a bit more complicated.  The GPU clock was something >1000GHz to begin with, which looked to be about a 60% loading but whilst I was still lapping it dropped to a 20% loading.

I will have to take another look tomorrow.
