The LeadTek software engineers are obviously not as artistically minded as those beavering away in Diamond's laboratory are. But what they lack in artistic grace, they more than make up for with practicality and sensible engineering. Within the control panel display adapter settings, LeadTek has provided a 'performance booster'. This performance booster allows you to set the speeds for both the memory and the graphics clock. A novel feature and something we're very likely to see in the near future for most TNT2 products. It was also good to see LeadTek providing a V-sync disabling feature (oops! There goes that Windows DirectX WHQL Certification). By now the gaming public knows only too well that turning the V-sync OFF increases frame rates considerably (albeit at a small price in terms of quality). Many of the larger competitors will NOT have this feature within their drivers due to the WHQL certification that seems to be so 'important' these days. Other than that, your usual gamma tweaking options and refresh rate settings, LeadTek has rehashed NVIDIA's reference drivers in terms of the OpenGL/D3D performance settings. LeadTek has apparently got 40% of their entire workforce working on R&D (that's a lot in this biz). Those of you that shy away from Windows 95/98 in favor of the more stable (but game unfriendly) Window NT will also be happy with NT 4.0 support.
