Recently i bought a new GPU a ATI Radeon HD 5450, the GPU is working fine in many games but i have a big problem when i play CS 1.6, while walking i get like 1 - 2 secs of lag and it's like the model want to give some steps back also sometimes my weapon has a glitchy reload, as far as i know this is called mouse/keyboard lag and it's common with ATI GPU's i haven't fixed it yet, i have tried a lot of things and tried different configs as well but nothing worked so i need your help please, here's my spec if they're needed
Everything already done and still have it, using OpenGL makes it worse, using 3D makes it take longer to start that annoying lag and software mode does make it happen BUT with software mode i can't use Steam Community and sometimes lag when go trought smoke
