|I have an emachines t5224 pc. I recently upgraded my graphics card from a bfg 8400gs 512mb to an ati radeon 128bit hd4650 gddr2 pci-e2.0 On my 8400gs, games went ok. games like bioshock coh, lostplanet, even lostplanet 2 at some parts, and crysis on medium settings. I played alot of more demanding games to. Now, i upgraded to an hd4650, and i see a huge performence increase in some games, but in most games Its very skippy and laggy, games that should work well doesint work well, some games never got an increase, and some played worse. overall my hd4650 is not performing as expected. i know its not a great g-card but i know it can play all games at medium -low settings. what is wrong with my g-card? is it my other parts of the system? It clearly seems like my graphics card is working below its ability.|
here are my specs,
Pentium D 820 @ 2.8GHz
2GB DDR2 RAM @667mhz
300w max powersupply
250GB SATA hard drive
Hd 4650 Gddr2 128bit pci-e2.0 graphics card.
also, I still have some of these prgrams called ntune, and nvidia performance phyx and stuff. But I cant uninstall it unless I take out my new card and put back in the old one. it says " cannot uninstall or operate without nvidia device."
Please someone help me I dont know why my games run like this, even older games like battlefield 2 and 2142 gets like 10-20 fps! and "can you run it" says i can run this game at highest settings. i'm also gaming at 1024x768.
