My laptop is 6 years old and has very low specs. Processor: Intel I5-7200 @2.50GHz RAM: 8 GB Graphics: AMD Radeon R5 M420 VRAM: 2039 MB Afterburner is causing problems. So, I have uninstalled Afterburner and using only Rivatuner Does Rivatuner work without Afterburner? Sorry for the dumb question
The OSD and the FPS limiter (including scanline sync) is implemented in RTSS. So you still got those. Afterburner provides the hardware monitoring, like CPU/GPU clocks and utilization, fan speeds, etc, as well as the overcloking and fan control. So you lose that functionality without Afterburner. However, you can use a different software to monitor hardware and display them in the OSD, like hwinfo, which supports RTSS. I believe AIDA64 also supports RTSS.
OverlayEditor plugin integrated into RTSS provides basic hardware monitoring core, which can be used in RTSS without MSI Afterburner or any other hardware monitoring data provider application.
