Good PC performance issue

[ryaanFS]

Hi all,

so i have a good gaming PC that i built in november last year. it has an i7 4790K,16GB DDR3 RAM and a GTX980

i love playing simulation games such as flight sim and most of all American truck simulator.

at first when i played american truck.i was getting 60FPS on ULTRA ALL THE TIME!!

there was absilutely no FPS drop and no shutters or anything. i was running the Geforce experience 361.91 driver.

i was also playing it in DX mode.

then one day i updated my Geforce experience driver and with DX mode i was now getting only 10-20 FPS on ultra,when before i used to get CONSTANT 60FPS.

i then went back to my old driver but it was the same! 10fps on ultra dx mode.

i then tried launching it with openGL which gave me back my FPS but it is no longer constantand i get loads of drops and full of shutterings specially when i turn or stuff like thta.i want to be able to play it again in dx mode without all the shutters.

any idea or solution?

thanks all replies are well aprreciated

Did you try to do a clean install of your drivers?

Well, try to format your PC, but before you do that. save all you desired data. there's millions of videos of how to format a PC. and i assumed that you have your disk of installation of windows and the key. in this case it doesnot matter if is a OEM or retail key. since you will format in the same pc with no change of the hardware. This should solve any problem that you computer have even if is a virus it anyway will be deleted. and is allways recommended to have a fresh start in sometime in a year.

There is a software that uninstalls all of your video card drivers so you can start fresh.  I don't remember the name at the moment.

haha just saw it in another thread.

I'm having similar problems, mine was being caused by the process "InstallShield Update Service Scheduler" and the specific file was issch.exe, which is a common windows program, but for some reason it was using all my cpu and ram when it would start running, and no game would go above 15 fps, regardless of settings, when they were pinned at like 80 fps with near max to max settings before. I made a thread about it with a lot more details, and pictures, but I'm telling anyone suffering from a sudden, massive performance drop like this, to see if they're not suffering from the same thing. I haven't solved it yet (hitting end task in task manager fixes it until the next computer reboot), as I'm not sure deleting the exe and containing folder will brick anything (since it's a common, useful bit of software that keeps background programs updated), but I do know that it's not supposed to be using noticeable resources, and definitely shouldn't be crippling my gaming performance. Check to see if it's causing your problems, before you go and wipe your system or something drastic like that trying to fix it.

If you go to Nvidia's website and download the latest driver, during the install wizard there's a checkbox for "Perform a clean installation". What this does, is uninstalls the existing driver and deletes and settings/preferences you may have and installs it as if there was never a driver on there before

I had a similar problem, everygame I used to play on ultra give me 15 or 20 fps including League of legends, something that is not logical because I have a GTX 780 and LOL doesn't require a lot of GPU process so I tried DDU to uninstall my gpu drivers but didn't work. So I did a clean windows installation and I cleaned my GPU and my FPS came back again

okay so i tried doing clean installs of all my drivers and also tried to clean install their latest driver...but nothing worked.the only i can get good fps BUT with TONS AND TONS of shutters and Drops is running it in OpenGl. i dont kow hwta to do.anyone have another advice?

Can you download and install MSI Afterburner, open the monitoring and run your game in windows mode? When you experience the stutters and drops, see what your GPU and CPU utilisation is.

okay sure ill try that and show u the results. thanks

okay so i just tested it in American truck simulator which is the game i play 95% of the time on my PC.

so as i said. i just cant launch it in dxmode! so i launched as i normally do in OpenGl mode on Ultra settings....

so my FPS stayed almost above 55FPS  in that session... the GPU Usage is NEVER  above 60% and its temp is around the 60s.

what i cant stand is the even small drops from 60 to 57 bcoz before it constantly stayed on 60.0 FPS it was as if locked there and could never go down. so yeah GPU usage was about 50-60% the whole time.

then i tried to ;aunch it in DX mode and miraculosly i got FPS in the 40s i say miraculosly bcoz before i always got like under 10 and way way before i always got CONSTNAT 60. so yeah in DX i was getting FPS  35-43. the GPU usage was great but i was jmping all over the place from like 70 to 99 but it was always above 90%. but one thing i did notice is that the temp was the same like if it was to be used 60%.

so i find that really weird that i get good FPS in Opengl with GPU used at 60% but i get only 40s with DX which is supposed to give m,e more FPS and that the GPU is used at the fullest.

any other idea? i really want to start playing it at coinstant 60FPS in DX Mode and that when i turn at a jucntion it does not shutter. anyone other idea? thanks for ur help bro

 

 

EDIT :::

 

u know i just noticed something. so i relaunches it in DX mode andd i was gettings 50-60fps in dx mode. then i closed the game and rrelaunched it and created a new profile and now it was less than 10 FPS and GPU usage was constant 100% but what i dont get is that the temperatire in DX mode when at 100% load is ALWAYS less than 50 degrees celcius and in opengl when used at only 60% it was in the 60 degrees how can DX at 100% be less than 50 degrees??? thats seems VERY VERY weird. !!!!!!!
