Hello Friends, Here is my configuration firstly, Windows 10 Pro 64 bit Intel Core i7 7700 3.60 Ghz (Turboboost upto 4.20 Ghz) 32 Gb Corair Vengeance ddr4 2400 Mhz. Gigabyte B250M-D3H Motherboard 600 Watts Power Supply Intel onboard Graphics 630(Vram upto 1 GB) ATI Radeon HD 4650 external GPU (GDDR2 1 GB) - Installed this from my old unit. Also cant afford a new GPU currently. Also this card only supports DirectX 10.1 Unfortunately Most current games only support DirectX 11 and upwards. I have tried every tweak possible including running DXCPL with Force Warp for games like Call of Duty Warzone so that i can atleast play under low settings. Also tried changing the registry values for ATI video card by making it 4 GB dedicated so that at least the Game reads the dedicated memory and starts. But no luck so far. My onboard Intel HD Graphics 630 has the similar issues. For eg, Call of duty Warzone starts and crashes @ cutscene. Here is the system requirements for COD Warzone. https://support.activision.com/call...nd-recommended-specs-for-call-of-duty-warzone Any tweaks that may help me ?
