DudleyAz Posted October 20, 2012 Share Posted October 20, 2012 I just took the plunge and spent the better part of a day overclocking the pc that runs my simpit. The only problem is I'm not seeing any improvement in my frame rates. :mad: I've had the PC for a couple of years, and took an initial try at overclocking when I first built it, but didn't have much luck so I've been running it stock. I've been wanting to get some higher frame rates in DCS A-10C, so I found this excellent walkthrough online about overclocking by Miahallen, and I was successful with the overclock, but I'm not seeing any impact in the sim. 34fps before AND after the OC. I don't get it?? With everything else being the same, seeing a 30%+ OC to the CPU, a 10% OC to memory, and a 10% OC to the GPU, you would think I would see at least a few frames higher performance wouldn't you? :helpsmilie: So I have a few specific questions: 1. Could there be another bottleneck somewhere in the system that would be keeping the frame rates down? If so, how do I address it? 2. On the overclocked video cards: I noticed that the Catalyst Control Center Overdrive Panel (where I did the overclocking) says that "The GPU clock settings will only be effective when the GPU is running in high performance mode". I am assuming that this kicks in automatically when the GPU is under load because testing using GPUz does report back that it operates at the overclock settings during the testing. Is there a way to manually set the GPU to use the OC settings all the time just to be sure? So here are the specs and details of what I've got and what I've done. All input is welcome, not just for me but for anyone else who may struggle with system performance issues (almost sounds like an ad for those little blue pills huh? ).

diveplane Posted October 20, 2012 Share Posted October 20, 2012 read the forums for answers .. search bar on top with a i7 cpu u should be getting semi decent performance, however the sim is in beta stage so framerates are still being adjusted. https://www.youtube.com/user/diveplane11 DCS Audio Modding.

Corrigan Posted October 20, 2012 Share Posted October 20, 2012 I would say that you should notice an improvement with that increase in CPU freq. One possibility I can imagine is that you're being limited by VRAM due to your high resolution. If you want, you could try with and without OC on a lower resolution (like on one screen).

Kuky Posted October 21, 2012 Share Posted October 21, 2012 (edited) I think you are limited by video card GPU1: XFX/Radeon HD 5830 1Gb overclocked to 900Mhz core & 1300Mhz memory driving 3x Benq E2400HD displays, each at 1920x1080 for 5760x1080 triple screen That video card is only 1GB vRAM and not that fast and to run 3 monitors is quite a hit on it. If overclock on CPU gains no FPS then it can only mean it's not the CPU that's being the bottleneck in that situation/ To overclock the video card you just do it in ATI CCC Performance tab. Set your desired clocks and click apply... when in 3D mode those clocks will be working. You can see my PC on bottom, I am running 3x 27" on HD7970 although I am not using all low settings as you, the performance hit is quite big when going from 1 camera viewport to 3 camera viewports... in case you are running 3 camera viewpoints you can swtich to 1 and larger FoV... it's not as nice as it gets strechign but will be much better on framerate.

Prophet Posted October 23, 2012 Share Posted October 23, 2012 Yep need 3 or more GB I would think. I don't know if the 5830 processor could handle more anyways though. Link to comment Share on other sites More sharing options...
Erforce Posted October 28, 2012 Share Posted October 28, 2012 I know i'm late, and i know i don't really know Core i, but give this a try http://forum.notebookreview.com/gaming-software-graphics-cards/569893-must-read-setfsb-o-c-game-problems-fixed.html wintestertimer should be synced. If it's not, follow the instructions, you will see fps gain afterwards.

Invisibull Posted October 28, 2012 Share Posted October 28, 2012 I would also try setting your shadows to high. Counterintuitive yes, but its helped many. i9 9900k - GTX 2080 Ti - MSI Z87 GD65 Mobo - 64GB HyperX Predator RGB DDR4 3200MHz - Win10 64 bit - TM Warthog w FSSB R3 mod - TrackIr 5.
