I have a P4 2.4 GHz with HT PC with 256MB Ram running windows XP Home and Intel 82865G Graphics controller card. Harry potter 2 Game played very well on my PC without any Problems. Recently I installed Harry Potter and Prisoner...... game. But while installing setup showed that my PC does not meet the requirement and game will be played in Software Rendering Mode. I agreed and installed the game. But after playing the game I saw that the software rendering is not at all good. It looks like I am playing an old game (Like DOOM 1). Even the resolution is 512*384 not 640*480. And I cannot change the resolution in the game at all. I set every video setting in the game to maximum, but things remain the same. I found in one cyber center the game is installed and the game played very well even through CPU is slow P3 1.7 GHz, running windows 98. But it has NVIDIA 32MB graphics card. In my computer the utility that shows system info comes with the game showed every requirement is O.K, Except that I have 248MB Ram, but required is 256MB Ram. Since my computer uses 8MB as video memory I have only 248MB Ram. Can anybody tell me how to change the rendering mode to Direct3D. I can play very well Need for Speed HP, UG Games at a resolution of 800*600 and even higher. I think I have to increase the RAM just to play this Game. Does anybody have any better IDEAS? Since this game has much better graphics than in Harry Potter and chamber of secrets Game I wanted to Play in Direct3D.
