Last view: 989 days ago 		Hi ! I'm still pretty new to emulation and everything related to it so sorry if the answer to my question was obvious or easily avaible somewhere else because I wasn't able to find it.

I can start the emulator without any issues in both OpenGL and Software (only in native resolution though). It starts and run fines when I'm on the menu of the games but when I actually start playing the games will lose a lot of frames and basically become unplayable. I suppose the main cause of it is my graphic card being an AMD Radeon R3.

Is there any way I can prevent this ?

If not what's the cheapest graphic card I could use to play at 60fps and eventually at a better resolution ?

Thanks for giving me your time.

(Edit : I have tried the emulator on Sonic Rush, Rayman DS and Yugioh world championship 2008 and all 3 have the same issues)

I can't exactly imagine a card from five years later performing at an unplayable rate, though it's probably worth posting your processor alongside the integrated card.

From what I can tell yours seems to be a mobile variant, so probably running at lower clock speed/power than the normal version, and pre-Ryzen AMD is generally worse for emulation than Intel due to far weaker single core/thread performance.

Yep I've already heard about AMD being crap compared to other brands. My processor is : AMD A4-9125 RADEON R3, 4 COMPUTE CORES 2C+2G 2.30 GHz

I suppose it's the cause of it then right ?

enable the JIT recompiler if you haven't already.


I wasn't able to find it. Where can I do that ?

the newer AMD processors are good.

Last view: 1008 days ago 		Comparison between mine and his processors

His single core performance is much lower, unfortunately - as mentioned his processor's a mobile one meant for a laptop. While I can see JIT helping, I'm not sure how much it will help in his regard. (The performance difference is even more evident on Linux than Windows, apparently, according to this page.)

Admittedly benchmarks aren't everything, but eh...
