vgilsoler Posted September 8, 2023 Share Posted September 8, 2023 I got a drop in FPS running the Baedecker Mission in the Channel Map. At the beginning and at the end of mission the FPS are constant at 60 FPS (the FPS are limited to Vsync) Even when flying around the bombers formation. Later the FPS down to 30 or even below 10 FPS. I deleted fxo and metashaders folder before launching the mission and take the FPS data. I also launched a windows performance monitor session to be sure the hardware resources are used by DCS and not by other software or service. I attach the track, dcs and debrief logs, the tacview data the performance monitor report and the sysinfo export (unfortunately it was took in spanish but I hope it could be useful for you) Let me know if you need I provide more details.

What is the mission time when the FPS drop occurs? --- Link to comment Share on other sites More sharing options...
Flappie Posted September 11, 2023 Share Posted September 11, 2023 I checked your track and I did not spot FPS drops, but I really need the mission time you start getting FPS drops so I can be sure I cannot reproduce your issue. I checked your sysInfo process list: I see you use OneDrive and ESET antivirus. Then I checked your DCS log: you're using a 130 GB pagefile! It's way too big. a 32 GB pagefile will do, considering you already have 32 GB of RAM (DCS can eat up to ~55 GB in total). 2023-09-08 20:01:28.141 INFO APP (Main): CPU cores: 4, threads: 4, System RAM: 32729 MB, Pagefile: 131072 MB Here are a few things you can try: Add DCS main path ("D:\SIMS\Eagle Dynamics\DCS World\") as to your ESET exceptions. Disable OneDrive before playing. See if it helps. Lower your pagefile to 32GB. --- Link to comment Share on other sites More sharing options...
vgilsoler Posted September 12, 2023 Author Share Posted September 12, 2023 I disabled one drive and DCS as already in the ESET exceptions. I've setup pagefile to 32GB. I repeated the mission again to get the time data: From T0 to T1000 aprox 60 FPS at T1000 to T1200 aprox 25 FPS at T1200 aprox 17 FPS at T1600 aprox 15 FPS at T1900 aprox 10 FPS at T2050 aprox 40 FPS From T2700 to the end 60FPS The results are few better than the first report. I did the mission in ST and it was worst than in MT. I attach the track and DCS log from this test. dcs_2.log BaedekerRaid_FPS_2.zip I7 3770K - 32 GB DDR3 - Nvidia RTX 4060 - SSD + NVME Link to comment Share on other sites More sharing options...
Solution Flappie Posted September 12, 2023 Solution Share Posted September 12, 2023 Thank you. This is what I get (AMD 3700X + GTX 1808Ti + 32GB of RAM): From T0 to T1000 aprox 90 FPS at T1000 to T1200 aprox 100 FPS at T1200 aprox 82 FPS Variations are much less important than on your PC. I see your PC is powered by an old CPU (i5-2550K, made in 2012) and your FPS sink when you're in the vicinity of bombers. I'm pretty sure your FPS counter reads "CPU bound" in red when your FPS sink. You should consider upgrading your PC, especially if you often fly missions with such large bomber formations. --- Link to comment Share on other sites More sharing options...
vgilsoler Posted September 13, 2023 Author Share Posted September 13, 2023 In that case the CPU requirements statement should be updated as this CPU is included for High Graphics settings. Specially if you have in mind that DCS in Single Thread does not matter how many cores the CPU has. CPU: Core i5+ at 3+ GHz or AMD FX / Ryzen; Thanks for your response.

Flappie Posted September 13, 2023 Share Posted September 13, 2023 I agree the requirements should be updated. I may be wrong about your issue, though. Please ensure your FPS counter reads "CPU bound" (in bright red) whenever your get these FPS drops. --- Link to comment Share on other sites More sharing options...
vgilsoler Posted September 14, 2023 Author Share Posted September 14, 2023 The CPU bond message in this mission is flashing. In other played missions it doesn’t do. I7 3770K - 32 GB DDR3 - Nvidia RTX 4060 - SSD + NVME Link to comment Share on other sites More sharing options...
