Thour ran tests to check the effect of anti-aliasing on PC performance in CS2
The tests were conducted on two PC configurations with 1920x1080 resolution and Reflex mode enabled.
On a mid-range PC with an i5-12400F processor, 1660Ti graphics card, 16GB ram , and Windows 10, the results were as follows: without anti-aliasing - 229.70 FpS , using CMAA2 - 221.30 FpS , with 2x anti-aliasing - 208.70 FpS , with 4x anti-aliasing - 198.50 FpS , and with 8x anti-aliasing - 162.10 FpS . The performance degradation at 8x anti-aliasing was 29.42% from no anti-aliasing.
On a more powerful PC with a 7800x3D processor, 4070Ti graphics card, 64GB ram , and Windows 11, the results were as follows: no anti-aliasing - 619.7 FpS , with CMAA2 - 610.3 FpS , with 2x anti-aliasing - 608.0 FpS , with 4x anti-aliasing - 600.1 FpS , and with 8x anti-aliasing - 547.9 FpS . The performance reduction at 8x anti-aliasing was 11.58%.
The test results show that using multi-sample antialiasing (MSAA) reduces FpS , especially on computers with less powerful configurations. On more powerful systems, the FpS reduction is less noticeable. If you have a mid-range computer, it is recommended to use no more than 2x MSAA to maintain optimal performance.
