FPS Results way off

[kurp999]

As image shows, my avg and 0.2% are way off from the actual numbers, while the 1% seems to be correct. Previously, on 1.7.4, I never had this issues. I have exceptions in Defender for ProgramFilesx86/CapFrameX and in Appdata. This also is only happening when doing Python automated 10-run benchmarks. Please let me know what I can do

First of all a capture file would be helpful for debugging.

Please post at least 3 of these capture files.

Here are 3 Bugged recordings that were done with 1.7.7 latest. Same process does not cause this issue in 1.7.6. Also these are done with benchmarking script in python as I said before, manual benchmark provides normal results.

These 2 were manual recordings that showed normal results as reference

Thanks for uploading the capture files. I have two points we should go through.

1. When you run automated benchmarks with the Python script, what are the entries in the process list (Running processes) on the Capture tab? If the list does include more than one entry, don't put it on the ignore list. Instead, please follow step 2.

2. Install the test build from here (no. 67): https://archive.capframex.com/ . Then go to %appdata%/CapFrameX/Logs and delete all files. Start an automated test using your script. After finishing the test, send us the new log file that should be created when running the benchmark.

Hey, no, I do not have any other running process, and I tend to manually select "cs2" instead of using auto-detection. I followed instructions and ran 5 automated benchmarks, the files are attached and still bugged. Thanks

As per the instructions, we need the log file from your appdata folder

Yeaaa my bad, im a little dyslexic

Ok, we need to check the native PresentMon behavior. Instead of using CapFrameX while running the benchmarks with the Python script, start PresentMon directly without any impact of CapFrameX. Go to C:\Program Files (x86)\CapFrameX\PresentMon then start cmd with admin rights, navigate to the folder, and type:

.\PresentMon-2.4.0-x64.exe --restart_as_admin --stop_existing_session --no_track_input --qpc_time_ms --track_pc_latency

PresentMon will create a csv file. Please post this file. You can stop the capture by pressing CTRL + C or just close the console.

Let me know if you need me to record for longer, the 1minute recording file was too large to upload unfortunately

My theory is that the ignore filter does not work properly. Please install build no. 70 from here: https://archive.capframex.com/

Run automated benchmarks and post the log file from %appdata%/CapFrameX/Logs. After that we should know the root cause.

[kurp999]

Here is log file + capture files just incase. P.S. the averages are still wrong

I have a question. When you did the benchmark with PresentMon directly, did you capture gameplay only, or does it include loading screen and menu navigation?

Also, can you please capture an automated benchmark (Python script) without sensor logging? You can disable sensor logging on the Sensor tab. One 60s run is enough, I think.

Here is a bugfix (build no. >=73): https://archive.capframex.com/

At least, I hope it's a bugfix. I've implemented a swapchain address filter. Your data showing a different address for the same process ID, which can be caused by game overlays for example.

Hey guys, I might have accidentally corrupted my windows drive while doing RAM OC, so I will not be able to test this for a few days. Please leave issue open for now, I will post once im back and stable on PC. Thanks a lot!
