wernst Posted September 3, 2018 Posted September 3, 2018 I wonder which generation of PCs is really needed for running DCS world 2.5 with decent fps. Which PC component has to be up to date, the CPU or the GPU, or both? I have a 10 years old intel i7 920 with 16 GB DDR3 RAM together with a 3 years old GTX 980. Most of the time I’m playing DCS single missions or free flight missions with system settings to HIGH. Under this conditions I can see in average 65 fps, but not less than 50 fps, with all modules and in all missions. Under full load the CPU heats up to max. 85 deg C (no OC). I'm a little worried that the CPU gets too hot, continuously. But the Win task manager surprisingly shows for CPU not more than 35% load. Could this be true and real? As consequence I ask myself: In which respect could I benefit from upgrading my trusty old i7 920 to the latest generation of CPUs, e.g. intel i7 8700K? (with new chipset MB and DDR4 RAM). I assume that the latest CPU will run cooler under full load, probably well below 75 deg C. But, besides VR, what else could be improved with a major CPU update?
TAW_Impalor Posted September 3, 2018 Posted September 3, 2018 Hi, depends on your screen resolution and whether you use VR. For 1080p your setup is enough. CPU temp depends on cooling, and default coolers are always insufficient and loud. Maybe put an external fan next to your PC. My specs are in signature, I use AIO watercooling for both CPU and GPU, fly exclusively in VR mostly at 45 fps with almost all eye candy on (and VR shaders mod). My CPU is old, but I won't upgrade until I see performance gain of at least 50%. Another bottleneck in VR are USB ports - so choose your next mobo carefully! 12900KF@5.4, 32GB DDR4@4000cl14g1, 4090, M.2, W10 Pro, Warthog HOTAS, ButtKicker, Reverb G2/OpenXR
Sandman1330 Posted September 3, 2018 Posted September 3, 2018 Regarding your CPU temps, as it is an older system, have you opened it up recently and cleaned out the dust? You CPU heatsink could be full of dust, which chokes airflow and causes temps to rise. A can of compressed air to all your heat sinks can do wonders for your temps.

BitMaster Posted September 3, 2018 Posted September 3, 2018 I would also consider to replace the thermal compound between heatsink and cpu after so many years, while you do that, clean it thoroughly :) Gigabyte Aorus X570S Master - Ryzen 5900X - Gskill 64GB 3200/CL14@3600/CL14 - Sapphire Nitro+ 7800XT - 4x Samsung 980Pro 1TB - 1x Samsung 870 Evo 1TB - 1x SanDisc 120GB SSD - Heatkiller IV - MoRa3-360LT@9x120mm Noctua F12 - Corsair AXi-1200 - TiR5-Pro - Warthog Hotas - Saitek Combat Pedals - Asus XG27ACG QHD 180Hz - Corsair K70 RGB Pro - Win11 Pro/Linux - Phanteks Evolv-X
Mars Exulte Posted September 3, 2018 Posted September 3, 2018 Sounds like your CPU has horrible airflow. You need to take a look at that before you fry it. As Bit said, new thermal compound, and consider a better heatsink/fan for it, too. 85C is about 30 degrees higher than you should be, especially for no overclock. -edit As for what is improved with a major update, the same things that are always improved with major PC updates. Higher framerates, higher transfer rates, etc, etc. If you're satisfied with your system, you don't need an upgrade. If you want more power, you need an upgrade. Either way, you def need to take a look at why your CPU is heating so badly. Де вороги, знайдуться козаки їх перемогти. 5800x3d * 3090 * 64gb * Reverb G2
Devrim Posted September 3, 2018 Posted September 3, 2018 Who plays world 2.5 on a 10 years old PC?Actually I have no that tough nerves as yours but, our PCs are similar tho. I have i7 2600 and GTX970. CPU alarm (in BIOS) is set to 80°C but never heard it. I think I'm on the edge of performance with this PC. A few months or one year later I will not able to see above 20 FPS. I can't buy new stuff today because of valueless of currency of my country. I'm suffering from FPS and low performance especially in crowded servers but... I can handle it somehow...

Holbeach Posted September 4, 2018 Posted September 4, 2018 85 deg, is close to fry up time. My, 7 yo, use to run low 80s, when OC, with the occasional shut down if a speck of dust landed on it. A new cooler (30 quid) immediately reduced temp by 15 deg. Regular vacuum with fan removed, is essential, even with case filters. Check fan is actually increasing correctly, with Asus history record. Today @ 3.8, my temp is 55 deg, running Harrier and room temp 23 deg. GPU same temp. Cooler is the key. Regards.. ASUS 2600K 3.8. P8Z68-V. ASUS ROG Strix RTX 2080Ti, RAM 16gb Corsair.

wernst Posted September 4, 2018 Author Posted September 4, 2018 (edited) Sounds like your CPU has horrible airflow. You need to take a look at that before you fry it.

Yes, you and Impalor, Sandman1330 and Bitmaster, you all are fully right. I uninstalled the cooler and fan and could see easily what was wrong. The lamella of the cooler unit were full of dust. And even worse, the thermal compound wasn't covering the heat sink area fully anymore and looked badly deteriorated. And, I have the impression that the fan was per design a bit weak (28 m3/hour air) Conclusion: bad maintenance, shame on me. It's a miracle how my trusty old i7 920 could survive so long in hellfire. Thank you intel, this CPU has passed a cruel long term test successfully. Action: A new cooler will be installed, NOCTUA NH-U9S with fresh thermal paste. I was misguided by looking at the CPU load only, which was never exceeding 35%. But even low load can be harmful when the heat isn't dissipated properly. Now it's the question how long the CPU still lives after the "refreshment". ----------------------------------------------------------------------------------------------- Edit: System: intel i7 920, GTX 980, 16 GB RAM, Samsung 500GB SSD 950 EVO DCS 2.5: free flight missions only settings: HIGH mon. res.: 1080p 10 years old CPU cooler: amb.

splash Posted September 4, 2018 Posted September 4, 2018 Mine reaches about 75-77ºC after some hours of playing DCS. I overclocked to 4.2 but no fps gains so I left it at 4 GHz. Probably you need to reapply thermal paste or change the cooler.
