Poor Performance on 4 cores

Strange. I get around 20-25fps on max detail, on a system that really should be doing better. However, if I set the games' affinity and make it run on 1 core, it performs around 60-70. Even weirder, I get glimpses of 120+fps on 4 cores, but only for about 20 seconds.

Specs:
Intel Core i5 6600K
Gigabyte Windforce GTX 970
16GB DDR4 RAM
Game installed on 1TB HDD

 

This was on Windows 10. Only GeForce Experience, Razer Synapse and Logitech Gaming Software are running in the background. This would happen on any car/track combo, any amount of AI drivers and any session. I have no mods installed, so all default content.

 

I must also add that some other games run poorly on 4 cores that really shouldn't, like Unreal Tournament 2004, so it's likely something with my system.

 

The game only runs on one core. Not sure what's going on. Do you have power saving mode enabled or something similar?

 

Power saving mode was precisely the issue. Switched to performance, and framerates are now what I expect.

PC is quite new, so it must've just been something I forgot to do.

 

Good to hear it's fixed, especially when it's something so simple, that's a nice win

Hope you can concentrate on enjoying the game now

 

I am having screen freezing on Formula Ultimate on many tracks after v1.4 update. Just me hotlapping. I have not tried any other cars, but will tonight. I was fine before (a few days ago). My system is overkill too. PC is running great on all other racing SIMS.

i5 7600 OC to 4.3Ghz, 16GB 2100 RAM, ASUS GTX1070. No nVidia Experience, but surround mode on three 24" ASUS 60hz monitors.

Tonight I will try un parking cores, checking power settings and may even try the ffb refresh rates. But is there something else related to V1.4 I need to know to make changes? I even deleted AMS and re downloaded through Steam.

 

I should have mentioned when I got spotter sounds is when it seemed to freeze, but wasnt 100% sure.

 

I turned postfx to low, didn't help. Had to turn off radio and spotter completely to stop sound problems and stutter/ freeze.

Things that helped, going into audio settings and changing all back to 44.1 from 48khz. After that change I could turn back on radio, but not spotter.

Computer was on balanced power. I have windows 10 btw. I have automobilista on an external drive, not on the ssd in my machine I believe.

 

I'll shoot a video tonight. Should clear things up.

 

Power on performance, turned back on spotter and post fx on low. Game crashes today (06/01/17) Will try and turn off spotter and see if I can get in car and drive.

After this video I went back into AMS and turned off spotter and turned off radio and kept post fx on low and it crashed again. I wont upload next video, but I'll see if I saved any from last night with the stutters and freezing, but I think I deleted them all.

 

@Domagoj I got the game to load by luck and was able to shoot this video. Notes in caption. Game is ok with AI, but not AI and spotter. Dont know if AI has anything to do with it. The video doesnt seem to capture all of the stutters I experienced. Also, is that high pitched whistle that flows up and down normal too? Can really hear it in the pit lane.

 

@Domagoj Lovric I was on quick removal. I changed to better performance. I hope it doesnt crash as it was crashing most of the night last night.

 

After update (06/04/17) all of my sound problems have been resolved. Thank you. I have radio/spotter back on with no problems.

edit: still there. At least i had one solo practice with the sound not causing stuttering. Now an intermittent problem for me.

 

by recommendation of Dann at Online Sim Racing I moved AMS from my external HD to the internal SSD drive and it runs very smooth again.

I guess since I am running low on memory on my main SSD I may need to buy another SSD and mount internally.
