Hello everyone! I am really struggling right now and want to ask for some help. Last week, I bought a Sapphire RX 5700 XT Nitro+ card. I deleted my old drivers with ddu and installed the new ones. Everything looked fine at first. But then, when I tried League of Legends, it was terrible! The game ran at 60 to 90 fps with drops down to 30 fps. Of course, this card is strong enough for that game but the performance is way too low. I checked my friend who bought the exact same card and he said his gets more than 140fps all the time.

I looked around looking for a problem but couldn't find anything. I tried everything on both Windows and Linux OS: Reinstalling the drivers, Flashing the GPU's bios, Checking for compatibility problems, Reinstalling the game, Testing the card with benchmarks and other games. Even tried the Linux open-source drivers 4 days later and still no improvement. The frustrating thing is that while the game struggles to render all the metrics are perfectly normal, even lower than normal. The GPU sits at 20% utilization, and all the CPU cores are at around 40% utilization. Also, all the temps are low around 80C on the GPU and 50C on the CPU. My system specs are: MSI B350 Tomahawk plus Ryzen 5 2400G Sapphire RX 5700 XT Nitro+ 16GB RAM @ 3200MT/s 500w PSU from Thermaltake Kingston NVME boot drive Windows 10 PRO, Linux Manjaro.

I am aware that the CPU only has an x8 PCIe slot for the GPU but I am pretty sure that is plenty of bandwidth for this GPU I also know that the 500w PSU is barely enough but I don't believe that is the bottleneck because all the usages are pretty low Any help will be much appreciated. Thank you in advance.

You are using a 500W power supply, and here is what AMD says for that card: "Recommended 650 Watt Power Supply (Minimum 600 Watt Power Supply)" https://www.sapphiretech.com/en/consumer...t-8g-gddr6 (scroll down to Specifications). That could definitely cause issues. Are you running GPU-Z in the background? You should check it. Pause any game, open the program, and go to the Sensors tab then scroll down to PerfCap Reason (Performance cap Reason). See what codes it is showing. When you hover over the word PerfCap it explains each code for you. My guess is you'll see Pwr, VRel, and/or VOp. All of these indicate not enough or unstable power. I think League of Legends is using your card harder than other games, so your card might be throttling because there isn't enough power coming in. Even if that's not the issue, you should seriously upgrade to a 750W PSU right now. You are pushing your current PSU too hard... and when they fail, they can take the whole system with them, frying the mobo or gpu. The EVGA SuperNOVA 750 G5 is a good choice. Trust me, make sure it is full modular. Only plug in the wires you actually need now, which looks cleaner and makes swapping much easier because you don't have to rewire everything. https://www.newegg.com/evga-superno...cription=psu&cm_re=psu-_-17-438-162-_-Product
