Edit: I was able to run some benchmark tests, so I don’t need help with this anymore, but after running the tests, I’m pretty sure my computer is having hardware issues. I don’t really have any other options, though, so I just have to deal with it.
The computer I was using stopped working and I had to switch to a different computer but despite having a significantly better GPU, games are performing only slightly better. I want to benchmark test the GPU to see if it’s a potential hardware problem or if something else is causing a bottleneck.
I use the unigine benchmarks sometimes. unigine-heaven and unigine-superposition (which btw is just cool to watch in my opinion). They provide linux packages here https://benchmark.unigine.com/ , check your distributions repos too though, some include these too though it’s rare. They are not open source, but games usually aren’t either.
The phoronix one that someone else posted also looks cool, I’ll have to try that one out next time I need something like this.
I tried to download unigine but I can’t seem to figure out how to download it. I’m using Linux Mint and the only download option seems to be a .run file which doesn’t seem to be executable in Mint. I also don’t know how to look through the repositories and when I tried to install “unigine-heaven” in apt, it told me it couldn’t find it in the repositories. So unless it’s called something else when you install it through apt, I don’t know how to download it.
Also, I did look into Phoronix but it only mentions that it benchmarks CPUs and not GPUs.
