Suddently low fps
Suddently low fps
Hi guys
Some weeks ago i suddently got low fps on everything i play (CP2077, Sea of Thieves, CS:GO)
It use to be around 60-70+fps i CP2077 with DLSS on and max settings, but now im low in late 20 mid 30. I have ran a Heaven Benchmark a couple of times and my score is 51fps/1400 points. I've checked my old score on a picture i had, and that old score was 98fps/2490 points. So almost the double of what i gets now.
I have checked clock mhz while running heaven and it is around 1500-1600mhz which ofc is low. temp is 75-79c all time so im not sure it is temp related. Newest driver and no OC. Power settings in Windows is set to Maximum performance.
I have both GPU and CPU in a custom waterloop.
PC spec:
X570 MB
Ryzen 5 3600
32gb 3200mhz ram
RTX 2080 Evga Black Gaming.
What can cause my fps drops?
Thanks

Based on that, it seems your GPU is experiencing thermal throttling, which also accounts for the decrease in FPS. When was the most recent time you cleaned and refreshed your loop? If you did so before, when? I discovered another user facing the same problem and after a thorough deep clean, their system performed exceptionally well. Here’s the link: Additionally, an open loop typically requires frequent maintenance, and it's recommended to flush your system at least once a year. While deep cleaning every two years is beneficial (involving taking the entire loop apart for thorough cleaning),
Have you attempted to remove or install drivers using the ddu method? Have you recently updated Windows? Many users have experienced their frame rates dropping significantly after the latest updates. The performance is severely impacted, with clocks showing much lower values than expected. It’s quite hot in a watercooled setup, around 75 to 79 degrees Celsius. I’d recommend inspecting the water loop and refilling the coolant. A watercooled card should ideally stay below 60 to 65 degrees, particularly when the clock readings are so low. Something seems amiss with either the loop or the cooling system.
Based on that, i'd say your GPU is thermal throttling. That also explains the drop in FPS. When was the last time you drained and flushed your loop? If ever? I found another user, who also had same issue and once he deep cleaned his system, he got it running like a charm, link: Btw, open loop needs most maintenance of all cooling solutions and you'd need to flush your system at least once a year. While it's good to do deep cleaning every 2 years (deep clean = take the whole loop apart and clean everything, while flushing the system with vinegar). Here's also JayzTwoCents vid how to flush (not deep clean) your system: View: https://www.youtube.com/watch?v=GqYQ-XnOPPI
I was thinking about the waterloop, but it was only five months ago when I changed the MB, so the entire loop was rebuilt back then.
The high temperatures might be due to using the Nzxt H510i Elite, which has a somewhat limited airflow, and the case is in a cabinet with the door open while the PC is running.
However, the PC has been inside the cabinet for over a year, and now only low FPS is appearing.
I removed the old Nvidia driver using DDU and have the latest Windows 10 update installed.
Would it cause discomfort when attempting to enhance your PC's cooling? Here, I'd remove the PC from its cabinet and place it on the desk, then open it up to clear out any dust. After that, perform stress tests to check if temperatures remain elevated and if the GPU throttles again, which might reduce FPS. If these steps resolve your problem, the issue was likely related to cooling. Otherwise, you may want to explore other potential causes.
Just did that, removed the PC and left it on the table with all panels off. Still getting around 70 FPS and the mid-700s. Actually managed a score of 1250 on Heaven Benchmark.

I'm not sure if the coolant issue is the main problem. I don't have any spare coolant, but I've ordered some, though I think I could use distilled water just to test. I understand that using only distilled water isn't ideal for extended periods, but this will be for about 2-3 days.
Well, distilled water is acceptable if you add anti-corrosion and anti-bacterial agents. Without them, the metal in your loop will corrode, and you'll start with life in the water, which can leave streaks on the water block. This effect is especially clear with transparent or see-through blocks.
Coolant might not be the sole issue either. Thermal paste or pads could also cause problems, as could the mounting pressure.
Even if I'm using distilled water for a day or two before getting my cryofuel, what do you think? Will I need to go through everything again and replace the paste and pads? Might it help to keep the original GPU cooler on hand just to compare?
