Because of my switch to a 24 TFT long time ago an the Release of ArmA 2. I baught a new GPU.
It is time to play my favorite Games in native Resolution 1920x1200 now also my TFT can handle the non native Resolution 1440x90 very good.
HD4870 with 2048 M VRAM
I know 2048 MB VRAM make no sense for other Games also on 25601600 TFT. GPU and CPU needs more Power.
And my CPU and my AGP/PCIE-DDR1/DDR2 Board is limited by ArmA2
4CoreDual-SATA2 with E5200 overclocked to 2x3.16 GHz because of Creative xifi that produces sound glitches with higer FSB also PCI is fixed to 33 MHz in Bios.
I have 2*2GB/800Mhz DDR2 limited to 3,3 GB limited by the Board and alternative Bios Firmware.
ArmA 1 and ArmA2 are placed on an Intel X25-M SSD drive.
I prefer Vista/Windows 7 64bit because they can handle HDD and VRAM much better. VRAM usage comes to 1 GB and higher, ArmA 2 cannot display Textures correctly with XP 32bit.
Both use newest ATI Tray Tool beta and Catalyst 9.6
I switched back to XP because I want to see the VRAM Usage in ArmA 2 (ATI Tray Tool, Everest, Rivatuner ...) Not possible with Vista or Windows 7.
I used the ATI Tray Tool Overlay.
very high/sehr hoch ... ArmA 2 ignores 1350 MB VRAM
I prefer very high/sehr hoch at the moment, because in many situations there are 15 frames more. To handle smal village fights or smoke.
On the other hand default/Voreinstellung has some nice advantages.
Switch to Sniper/Google Optics, approaching big city, flying or driving through whole world or playing on busy servers which limit client frame rate.
Exploring in Editor with 20 FPS/default is same situation is nicer than 30 FPS/very high.
In ArmA 1 I use default/Voreinstellung because the Requirements spend less resources. The handling with textures and objects is very smooth and I have enough frames.
