Simon81 Posted October 21, 2015 Posted October 21, 2015 (edited) Hi there, Can anybody explain me the problem I get on my PC? Here's my specs: AMD FX-8320 X8 3,5GHz BOX (stock, no OC) ASUS STRIX GTX970 (Stock, no GPU boosted) ASUS M5A99X EVO R2.0 Fortron ATX HEXA 500W Kingston KHX1866C11D3P1K2/8G SSD KINGSTON SV300S3B7A/120G HDD WD Green WD20EZRX 2TB SATA III 64MB. FreeTrack 2.2 with PS3 Camera Single Monitor 1080p: 1842x1036 And with all these all I can get in DCS 1.5 with max settings (DOF OFF, CIV TRFC OFF) is about 17-20FPS during take off... (DCS->Instant action-> Mig-21-> take off hot sortie)... Then it's gettin better, but it goes only to a ~60FPS (which is fine, but it's not stable) I've noticed, that when I get near to the airfield the FPS goes down rapidly. And now the best part: I lower the DCS performance to lowest possible settings and results were almost the same... Now I run out of ideas. I had better performance on R7 260 which I've changed to a GTX970 yesterday. I spent almost whole day to check what could be wrong, Can anybody help me with these please?

tintifaxl Posted October 21, 2015 Posted October 21, 2015 Same fps with R7 260 and GTX970? To me it looks as if your cpu is the culprit of the low performance and not the gpu. Windows 10 64bit, Intel i9-9900@5Ghz, 32 Gig RAM, MSI RTX 3080 TI, 2 TB SSD, 43" 2160p@1440p monitor.
Wynthorpe Posted October 21, 2015 Posted October 21, 2015 Did you format your PC going from the AMD to the Nvidia?
Simon81 Posted October 21, 2015 Author Posted October 21, 2015 No, comp wasn't formated, just unistalled AMD Drivers and after changing GPU's I installed new one from Nvidia.
Bewsher Posted October 21, 2015 Posted October 21, 2015 Powersupply looks like it cant handle the GPU. Replace with a 700 watt or higher. This will help you upgrade easier later on.
OnlyforDCS Posted October 21, 2015 Posted October 21, 2015 Wish I could help but I have an i5 processor and can't really comment on the performance of AMD CPUs but I believe that your CPU is the culprit. Maybe someone with a similar CPU+GPU setup can comment on the performance? One other thing to consider, the 1.5 Beta is memory hungry, and may have some memory leaks. Have you tried to run the stable non beta 1.2.X version to check how performance is there?

fixen Posted October 21, 2015 Posted October 21, 2015 (edited) PSU should be ok. Fortron is a decent brand and this does not seems like a PSU issue. I suspect it has more to do with the bèta. Though your CPU is not very powerfull, you should get better frames. I have a i5 4690K and GTX 970 and my frames are much better. The thing I always do when buying new parts is a complete reinstall. But I understand that not everyone wants to do that. Edit: I just read that the 4690k has 81% better single core performance than a 8320. So you are going to lose some frames there.

Brisse Posted October 21, 2015 Posted October 21, 2015 (edited) Powersupply looks like it cant handle the GPU. Replace with a 700 watt or higher. This will help you upgrade easier later on. Bad advice for two reasons. 1. The GTX970 is an efficient card. It doesn't need much power. 2. Those are not the symptoms of an undersized PSU. If you have too small PSU, the graphics card will still draw as much power as it needs, but the PSU will be running over it's specification and eventually the over-current protection kicks in and just shuts down the whole PC. Wish I could help but I have an i5 processor and can't really comment on the performance of AMD CPUs but I believe that your CPU is the culprit. Maybe someone with a similar CPU+GPU setup can comment on the performance? I have FX-8350 which is similar CPU and it runs just fine. Typical frame-rates I see are 70-125 fps with the 1.5 open beta. Can't blame the CPU. My advice would be to make sure you have the latest driver, which you probably have already, and then get some third party software (like Asus GPU Tweak II) to monitor the GPU clock-speed. It could be that it's stuck in 2D mode which runs at reduced clock-speeds to improve power consumption. Edited October 21, 2015 by Brisse

Can't blame the CPU. Your post confirms it is very likely a problem with his setup. For reference, do you also have a GTX970? Unfortunately that means that it could be any number of things. I still think it's related to his CPU as he has noted that changing his graphics options has had no effect on the performance. A bad cooling solution, or an improperly placed cooler would cause very poor performance, it could also be something running in the background like a trojan or virus which is eating up CPU cycles. To the OP: what kind of temperatures are you getting with your CPU when checking BIOS and third party programs?

I had this exact issue going from a R9 290X to a GTX980, Must be some remnants left over somewhere, to be honest id format and start afresh with this type of change, but thats just me. BTW I run a OCZ 550W PSU and have no issues at all running an overclocked system and GPU.
Simon81 Posted October 21, 2015 Author Posted October 21, 2015 (edited) Before i start bothering You here i've read almost all info bout fps loss in DCS conected with gtx 970. I've download latest nVidia drivers and made custom clean instalation, then start to change nVidia 's settings (read bout set AA,and same others stuff under control of aplication) -nothing changed in DCS fps. Then start to tune GPU with GPU Tweak, I done this till system loss stability. IT was weird for me, cause one of my friend got with this card 66fps stable with all settings maxed in DCS and all of the nVidia and GPU settings stock... Whats also noticed while monitor gpu that card is almost unused, maybe 1\3 of it resources is in use... Edited October 21, 2015 by Simon81
Bewsher Posted October 21, 2015 Posted October 21, 2015 Good to know about the PSU rating. Just assumed bigger is better. Yep he should format completely.
dburne Posted October 21, 2015 Posted October 21, 2015 Personally I would try cleaning out all remnants of any display drivers first, then doing a clean install of the latest Nvidia drivers. There easily could have been some remnants of the AMD drivers left over. I would recommend Display Driver Uninstaller ( DDU). First uninstall the Nvidia drivers. Then run this program, and let it search for any remnants left, first of the Nvidia drivers, then of the AMD drivers. Clean everything out that it comes up with. Then do a fresh install of the Nvidia drivers, installing only the drivers and PhysX. I would give this a shot before resorting to a reformat of everything.

Yurgon Posted October 21, 2015 Posted October 21, 2015 Very good advice, and can be done in 5 minutes. Agreed, would be my first choice as well. I think I remember similar problems posted by someone else not so long ago. In that case, he'd plugged the monitor to the mainboard's DVI-connector and never used the new graphics card. If I recall correctly, substantial amounts of booze were involved and things cleared up the next day. :D
Brisse Posted October 21, 2015 Posted October 21, 2015 Your post confirms it is very likely a problem with his setup. For reference, do you also have a GTX970? No, I have the R9 290X, but it's in the same price and performance range as the GTX970. I had this exact issue going from a R9 290X to a GTX980, Must be some remnants left over somewhere Should be easily fixed with DDU. No need to format or reinstall Windows :) http://www.guru3d.com/files-details/display-driver-uninstaller-download.html
Simon81 Posted October 21, 2015 Author Posted October 21, 2015 Ok Guys, tommorow I come with artillery and bring someone who knows computer hardware and software better than I do. BIG Thx for all Your advice, DDU is downloaded and waitin' for use. Tommorow I can tell is it finally work as I expected when buying GTX or if the dark clouds are upon me and nothing can be done...
Gerg Posted October 22, 2015 Posted October 22, 2015 Are you using max msaa and other settings? Can you post screenshot of your graphics menu options pls.
Simon81 Posted October 22, 2015 Author Posted October 22, 2015 (edited) Ok. I think I found the problem. It was about aspect ratio, which was quite weird (1.77777778 ) and I wasn't able to change it (because then DCS crashes) After some try I discover, that after the another crash fianaly aspect ratio was changed somehow to 16:10 and from then everything runs smoother and got nicer fps. Now I got my CPU overclocked to 4.4 (from 3.5) and tonite will test it longer about temperature and stability. GPU will be next to tune. As a reference situation to measure the fps I use from "Instant action" the Mig-21bis take off. Now when on the ground before take off run (with Mi-24's aside) and looking directly fwd i got ~24-27fps. Budy of mine with the same GTX970 but Intel CPU's got around the same numbers (~29-34). After take off fps go over 90-110 and are pretty stable at maxed settings. Edited October 22, 2015 by Simon81
Gerg Posted October 22, 2015 Posted October 22, 2015 (edited) I think you are still asking too much of your system. On 1.5 changelog it says the new "Extreme" visibility is only for high end systems along with a few other options that are set probably too high for the cpu/gpu. Id try lowering the visibility range one notch along with the shadows options, water and cockpit displays res down to 512. Might as well turn vsync on too and get a stable 60 fps instead of thrashing the gpu for extra fps the screen wont show (if a 60hz screen). Edited October 22, 2015 by Gerg
dburne Posted October 22, 2015 Posted October 22, 2015 Id try lowering the visibility range one notch along with the shadows options, water and cockpit displays res down to 512. I have found at least in the Ka-50, having cockpit displays set to 1024 is a real frame rate killer when there is action going on in the Abris display, especially things blowing up. Set to 512, even 512 every frame, no frame rate hit to speak of.

No problems here, also with a GTX970. Except for screen resolution. I have that set to 512.

With what cpu though? The FX-8320 has about the same single core performance as a Core2Duo e6600 2.4 ghz. I still dont think DCS 1.5/2 supports multi core cpus (or 2 cores max) so its the equivalent of running the 970 with a 9 year old core2duo.

I'm seeing 70 - 125 fps rendering at 1440p and everything on high. Edit: Took a screenshot just to demonstrate. As you can see, there's plenty of CPU headroom and the framerate is fine. This is from the first A-10C quick start mission. Edited October 25, 2015 by Brisse

Does the cpu load change at all when on the runway or just the gpu load increases? It always drops loads of fps for me on the ground.
