All these "solutions" seem to be coincidence I think you guys really need to look at processes running (in your task manager) and see what's eating up CPU cycles. I'm going to guess it's most likely Windows Defender or some other sort of anti-virus/anti-malware program running a scan on RO2 for some reason.
I say coincidence because eventually the scan stops and your game returns to normal while you've been messing around with settings or looking for solutions.
After a good grind, this same issue happened for me.
Looking through this thread trying the different solutions, this seemed to make sense. Checking Task Manager and processes running, I noticed my CPU usage was going to a program called MsMpEng.exe (Antimalware Service Executable). Upon closing RO2, which was displaying low FPS in the login screen from the get-go, the CPU usage dropped for the program. Opening RO2 caused the program to reactivate, leading to low FPS once again. So building on thegir's post, I agree there is a process conflict with RO2 and the antimalware program.
With Google being my friend and some research, the program is usually associated with users running MSE (Microsoft Security Essentials) and/or Windows Defender.
The solution is a bit iffy though. So
MY immediate response would be to end the process.
What happens is an "access denied," which the process wouldn't close. Something I couldn't get around. Running MSE, I checked if there was any scans happening. None. I check Windows Defender (
which should be turned off if running MSE) and get prompted to turn it on.
This is where it gets iffy. With the game running in the background, I click to turn on Windows Defender; what happens is a program stall while in the meantime RO2 kicks back to a stable FPS. I had to force close Defender since it was stuck, but upon reopening, it was still turned off.
With Defender off, MSE running, and RO2 stable, I didn't question it, everything was back to normal. I thought to contribute to anyone that can verify and/or build upon my half-butt solution.
INSTRUCTIONS (Run RO2 in the background):- Go to Control Panel
- Find Windows Defender. Open.
- Depending if you're running MSE, it should be already turned off.
- Turn it on. (If already on, let me know. I wouldn't know of this scenario yet.)
- What happens is the window getting frozen. Check RO2 to see any changes.
- If none, force close the frozen program and check again.
- If it works or not, leave feedback. For credibility, please check your own security software to see if it's still running for those skeptical about making any unknown changes.
From what I have observed, it seems to reset the background program conflicting with RO2.
Responses and feedback from friends so far works. Any questions or concerns please ask.
UPDATE:So far I have one person not getting a fix from this solution. Helping him out with possible fixes, will update eventually.
UPDATE 2:We were able to get it working after restarting his computer and trying the process all over. He seemed to be able to turn on Windows Defender and view the menu, but froze after a few seconds. In the meantime, his RO2 picked back up and worked.
